elasticsearch: search within text - elasticsearch

For example if name as P.Shanmukha Sharma and if user searches for Shanmukha will not be available for search result. its returning only for P.Shanmukha and Sharma, is there any way if i will search Shanmukha and it will return result?
"user" : {
"properties" : {
"city" : {
"type" : "string",
"analyzer" : "autocomplete",
"search_analyzer" : "standard"
},
"created" : {
"type" : "date",
"format" : "strict_date_optional_time||epoch_millis"
},
"id" : {
"type" : "long"
},
"latitude" : {
"type" : "double"
},
"longitude" : {
"type" : "double"

"profile_image" : {

"state" : {

"super_verification" : {

"type" : {
"type" : "string"
},
"username" : {
"type" : "string",
"analyzer" : "autocomplete",
"search_analyzer" : "standard"
}
}
}
username is defined as a search analyzer
and search query is
def EsSearch(self, index, page, size, searchTerm):
body = {
'query': {
'match': searchTerm
},
'sort': {
'created': {
'order': 'desc'
}
},
'filter': {
'term': {
'super_verification': 'verified'
}
}
}
res = self.conn.search(index=index, body=body)
output = []
for doc in res['hits']['hits']:
output.append(doc['_source'])
return output

so doing so much of research on ES i Got this solution with wildcard. Thanks EveryOne
{
"query": {
"wildcard": {
"username": {
"value": "*Shanmukha*"
}
}
}
}

Basically, 2 way in to do so,
By GET method and URL:
http://localhost:9200/your_index/your_type/_search?q=username:*Shanmukha*&pretty=true
By Fuzzy Query

How to query in parent-child relation in elasticsearch

I have parent-child relation for Customer(Parent) and PromotionCustomer(Child).
Customer data:
{
"id": "b7818d4d-566e-24f5-89d2-3995bb97fd5e",
**"externalId": "9200191",**
"name": "LOBLAW NFLD",
"fullName": "LOBLAW NFLD",
"businessSystem": "EBJ/001"
}
PromotionCustomer data:
{
"id" : "31f2e065-a046-9c3a-808b-83545ddb07d1",
"externalId" : "T-000195542",
"businessSystem" : "EBJ/001",
"promotionDescription" : "PM-RT-LOBLAW NFLD-BB",
"promotionType" : "Bill Back",
"promotionStatus" : "Approved",
**"promotionCustomer" : "9200191",**
"validFrom" : "02/28/2019",
"validTo" : "03/20/2019",
"promotionDateTypeCode" : "1"
}
This the mapping details(schema)
{
"promotionsearch" : {
"mappings" : {
"properties" : {
"_class" : {
"type" : "text",
"fields" : {
"keyword" : {
"type" : "keyword",
"ignore_above" : 256
}
}
},
"customer" : {
"type" : "nested",
"include_in_parent" : true,

},
"id" : {
"type" : "text",
"fields" : {
"keyword" : {
"type" : "keyword",
"ignore_above" : 256
}
}
},
"promotioncustomer" : {
"type" : "nested",
"include_in_parent" : true,
"properties" : {
"businessSystem" : {
"type" : "keyword"
},
"externalId" : {

},
"promotionProducts" : {

},
"promotionStatus" : {
"type" : "keyword"
},
"promotionType" : {
"type" : "keyword"
},
"validFrom" : {
"type" : "date",
"format" : "MM/dd/yyyy"
},
"validTo" : {
"type" : "date",
"format" : "MM/dd/yyyy"
}
}
},
"promotionjoin" : {
"type" : "join",
"eager_global_ordinals" : true,
"relations" : {
"customer" : "promotioncustomer"
}
},
"routing" : {
"type" : "text",
"fields" : {
"keyword" : {
"type" : "keyword",
"ignore_above" : 256
}
}
}
}
}
}
}
I need to get the get the promotionCustomer data based on the externalId which is the customerId which maps to promotionCustomer along with the date range.
I've written a query as below.
GET /promotionsearch/_search
{
"query": {
"has_parent": {
"parent_type": "customer",
"inner_hits": {},
"query": {
"has_child": {
"type": "promotioncustomer",
"query": {
"bool": {
"must": [
{
"match": {
"customer.externalId": "9200191"
}
},
{
"range": {
"promotioncustomer.validFrom": {
"gte": "02/28/2019"
}
}
},
{
"range": {
"promotioncustomer.validTo": {
"lte": "03/20/2019"
}
}
}
]
}
}
}
}
}
}
}
But it's not yielding the result. I know the reason as well. In the has_child clause i'm making use of parent field i.e "customer.externalId". Is there a way to include/add this condition in the parent_type query and then based on the result apply range condition inside has_child
I was able to get the solution. Hope it helps others as well. No need make multiple query call to ES inorder get the desired result.
GET /promotionsearch/_search
{
"query": {
"bool": {
"must": [
{
"match": {
"promotioncustomer.promotionDescription": "PM-RT"
}
},
{
"range": {
"promotioncustomer.validFrom": {
"gte": "02/28/2019"
}
}
},
{
"range": {
"promotioncustomer.validTo": {
"lte": "03/28/2019"
}
}
},
{
"has_parent": {
"parent_type": "customer",
"query": {
"match": {
"customer.fullName": "sdjhfb"
}
}
}
}
]
}
}
}

Elasticsearch multi_match + nested search

I am trying to execute a multi_match + nested search in ElasticSearch 6.4. I have the following mappings:
"name" : {
"type" : "text"
},
"status" : {
"type" : "short"
},
"user" : {
"type" : "nested",
"properties" : {
"first_name" : {
"type" : "text"
},
"last_name" : {
"type" : "text"
},
"pk" : {
"type" : "integer"
},
"profile" : {
"type" : "nested",
"properties" : {
"location" : {
"type" : "nested",
"properties" : {
"name" : {
"type" : "text",
"analyzer" : "html_strip"
}
}
}
}
}
}
},
And this is the html_strip analyzer:
"html_strip" : {
"filter" : [
"lowercase",
"stop",
"snowball"
],
"char_filter" : [
"html_strip"
],
"type" : "custom",
"tokenizer" : "standard"
}
And my current query is this one:
"query": {
"bool": {
"must": {
"multi_match": {
"query": 'Paris',
"fields": ['name', 'user.profile.location.name']
},
},
"filter": {
"term": {
"status": 1
}
}
}
}
Obviously searching for "Paris" in user.profile.location.name doesn't work. I was trying to adapt my code to following this answer https://stackoverflow.com/a/48836012/12007123 but without any success.
What I am basically trying to achieve, is to be able to search for a value in multiple fields, this may or may not be nested.
I was also checking this discussion https://discuss.elastic.co/t/multi-match-query-string-with-nested-and-non-nested-fields/118652/5 but everything I tried wasn't successful.
If I just search for name, the search is working fine.
Any tips on how can I achieve this the right way, would be much appreciated.
EDIT:
While I didn't get an answer to my initial question, I was following Nikolay's (#nikolay-vasiliev) comment and changed th mappings to Object instead of Nested.
At least now I am able to search in user.profile.location.name. This is how the new mapping for user looks like:
"user" : {
"properties" : {
"first_name" : {
"type" : "text"
},
"last_name" : {
"type" : "text"
},
"pk" : {
"type" : "integer"
},
"profile" : {
"properties" : {
"location" : {
"properties" : {
"name" : {
"type" : "text",
"analyzer" : "html_strip"
}
}
}
}
}
}
},

Must match query is not working in elastic search

I am tying to find all Videos with the name "The Shining"
but also with a parent_id = 189, and parent_type = "folder"
My query seams to connect all of the match statements with "OR" instead of "AND"
What am I doing wrong?
{
"fields": ["name","parent_id","parent_type"],
"query": {
"and": {
"must":[
{
"match": {
"name": "The Shining"
}
},
{
"match": {
"parent_id": 189
}
},
{
"match": {
"parent_type": "folder"
}
}
]
}
}
}

}
}
},
"uid" : {

},

}
}
}
}}}
I was able to solve the problem by reading Volodymryrs answer above.
Aditional matches were being found because they were matching "the". I tried to add the operator argument, but that did not work unfortunately. What I did instead was to use "match_phrase" and also switched my two other match fields to "term" - see my answer below –
[
'query' => [
'bool' => [
'must' => [
[
'match_phrase' => [
'name' => $searchTerm
]
],
[
'term' => [
'parent_id' => intVal($parent_id)
]
],
[
'term' => [
'parent_type' => strtolower($parent_type)
]
]
]
]
]
];
You will get matches on the or shining because of match query, and depending on matches you will get score. One of the easiest fixes would be to add operator and:
{
"match": {
"name": "The Shining",
"operator": "and"
}
}
But it's not what you need since this will also match names "shining The" or "The sun is shining".
Other option is that if you need to do exact matches on name, then you would need to make field name as non-analyzed. In ES 5 you can set field type as a keyword
In addition I would recommend you to use bool query with term queries since they will do exact match.
{
"fields": ["name","parent_id","parent_type"],
"query": {
"bool": {
"must":[{
"term": {
"name": "The Shining"
}
},
{
"term": {
"parent_id": 189
}
},
{
"term": {
"parent_type": "folder"
}
}
]
}
}
}

Mysteriously wrong values of numerical fields in ElasticSearch

I've spent the last 2 days investigating this mind-bending issue:I have an index with custom mappings on which I perform some aggregations. The problem is that in the results of the aggregation on numerical fields,it returns values that do not appear in the database from which the data was imported, even though the number of results is the same.
I found a similar issue here where the problem was inconsistent mapping of a field across an index, but in my case it is mapped as the same type. The problem happens with the fields: award.value.amount, award.value.x_amountEur, tender.value.x_amountEur as far as I have checked.This is my current mapping as stated by curl -XGET 'http://localhost:9200/documents/_mappings?pretty&human'

This is the aggregation I am using in order to get the values of contracts between each pair of supplier - procuring_entity:
Document.es.search({
"search_type": "count" ,
"body":{
"aggregations": {
"entities":{
"nested": {
"path": "procuring_entity"
},
"aggs": {
"procuring_entity_names": {
"terms": {
"field": "procuring_entity.x_slug",
"size": 0
},
"aggs": {
"suppliers": {
"nested": {
"path": "suppliers"
},
"aggs": {
"suppliers_names": {
"terms":{
"field": "suppliers.x_slug",
"size": 0
},
"aggs": {
"awards": {
"nested": {
"path": "award.value"
},
"aggs": {
"award_amounts": {
"terms":{
"field": "award.value.x_amountEur",
"size": 0
}
}
}
}
}
}
}
}
}
}
}
}
}
}})
The result with type float is :
{"entities"=>
{"doc_count"=>24300,
"procuring_entity_names"=>
{"doc_count_error_upper_bound"=>0,
"sum_other_doc_count"=>0,
"buckets"=>
[{"key"=>"vsia-bernu-kliniska-universitates-slimnica",
"doc_count"=>1360,

{"doc_count"=>1360,
"suppliers_names"=>
{"doc_count_error_upper_bound"=>0,
"sum_other_doc_count"=>0,
"buckets"=>
[{"key"=>"recipe-plus-as",
"doc_count"=>388,
"awards"=>
{"doc_count"=>388,
"awards"=>
{"doc_count_error_upper_bound"=>0,
"sum_other_doc_count"=>0,
"buckets"=>
[{"key"=>3679.086669921875, "doc_count"=>373},
{"key"=>0.0, "doc_count"=>12},
{"key"=>73610.3203125, "doc_count"=>1},
{"key"=>244000.0, "doc_count"=>1},
{"key"=>342348.9375, "doc_count"=>1}]}}}
The problem is that in MongoDB the same query returns 388 documents that all have award.value.x_amountEur = 3679.08661250056 , as presented by Mongoid query:
Document.where(:"procuring_entity.x_slug" => "vsia-bernu-kliniska-universitates-slimnica")
.keep_if{|doc| doc.suppliers.first.x_slug == "recipe-plus-as"}
.map{|doc| doc.award.value.x_amountEur}.uniq
=>[3679.08661250056]
A query directly into MongoDB returns the same.
I have also tried to map the targeted fields as double, which gave the same result and as long which returned the following (even more incorrect result):
{"entities"=>
{"doc_count"=>24300,
"procuring_entity_names"=>
{"doc_count_error_upper_bound"=>0,
"sum_other_doc_count"=>0,
"buckets"=>
[{"key"=>"vsia-bernu-kliniska-universitates-slimnica",

{"doc_count"=>1360,
"suppliers_names"=>
{"doc_count_error_upper_bound"=>0,
"sum_other_doc_count"=>0,
"buckets"=>
[{"key"=>"recipe-plus-as",
"doc_count"=>388,
"awards"=>
{"doc_count"=>388,
"awards"=>
{"doc_count_error_upper_bound"=>0,
"sum_other_doc_count"=>0,
"buckets"=>
[{"key"=>3679, "doc_count"=>371},
{"key"=>0, "doc_count"=>12},

{"key"=>331636, "doc_count"=>1},
{"key"=>342348, "doc_count"=>1},

I'm using Elasticsearch 2.0, mongoid 5.0.1 and mongoid-elasticsearch for indexing. I can't think of anything else to do so any suggestion is welcomed and appreciated.
I tried to test your scenario with ES 2.0 and there is something that I'm missing. I cannot make it create buckets for the award.value.x_amountEur unless I use a reverse_nested aggregation to "get out" from one nested path and into another.
So, instead of the awards aggregation that you have I'm using the same aggregation but "wrapped" in a reverse_nested aggregation:
"aggs": {
"getting_back": {
"reverse_nested": {},
"aggs": {
"awards": {
"nested": {
"path": "award.value"
},
"aggs": {
"award_amounts": {
"terms": {
"field": "award.value.x_amountEur"
}
}
}
}
}
}
}
And for this one I am seeing something ok.
Later edit: following mine and more general #Val's suggestion, the complete solution was to use reverse_nested on both awards and suppliers aggregations.

how to change type of a value in elasticsearch

I am trying to do geomap of a value in Elasticsearch but the value type of the client_location is set as a string and I would like to change it to geo_point. When I run the following I am getting:
#curl -XGET "http://core.z0z0.tk:9200/_all/_mappings/http?pretty"
{
"packetbeat-2015.12.04" : {
"mappings" : {
"http" : {
"properties" : {
"#timestamp" : {
"type" : "date",
"format" : "strict_date_optional_time||epoch_millis"
},
"beat" : {
"properties" : {
"hostname" : {
"type" : "string"
},
"name" : {
"type" : "string"
}
}
},
"bytes_in" : {
"type" : "long"
},
"bytes_out" : {
"type" : "long"
},
"client_ip" : {
"type" : "string"
},
"client_location" : {
"type" : "string"
},
"client_port" : {
"type" : "long"
},
"client_proc" : {
"type" : "string"
},
"client_server" : {
"type" : "string"
},
"count" : {
"type" : "long"
},
"direction" : {
"type" : "string"
},
"http" : {
"properties" : {
"code" : {
"type" : "long"
},
"content_length" : {
"type" : "long"
},
"phrase" : {
"type" : "string"
}
}
},
"ip" : {
"type" : "string"
},
"method" : {
"type" : "string"
},
"notes" : {
"type" : "string"
},
"params" : {
"type" : "string"
},
"path" : {
"type" : "string"
},
"port" : {
"type" : "long"
},
"proc" : {
"type" : "string"
},
"query" : {
"type" : "string"
},
"responsetime" : {
"type" : "long"
},
"server" : {
"type" : "string"
},
"status" : {
"type" : "string"
},
"type" : {
"type" : "string"
}
}
}
}
}
}
When I run the following command to change the type of the value from string to geo_point I am getting the following error:
# curl -XPUT "http://localhost:9200/_all/_mappings/http" -d '
> {
> "http" : {
> "properties" : {
> "client_location" : {
> "type" : "geo_point"
> }
> }
> }
> }
> '
{"error":{"root_cause":[{"type":"merge_mapping_exception","reason":"Merge failed with failures {[mapper [client_location] of different type, current_type [string], merged_type[geo_point]]}"}],"type":"merge_mapping_exception","reason":"Merge failed with failures {[mapper [client_location] of different type, current_type [string], merged_type [geo_point]]}"},"status":400}
Any suggestion how should I correctly change the type?
Thanks in advance.
Unfortunately, once you've created a field you cannot change its type anymore. The best thing to do is to delete the index and recreate it properly with the adequate mapping.
Another temporary solution if you don't want to delete your index immediately, is to create a sub-field of your existing field:
# curl -XPUT "http://localhost:9200/_all/_mappings/http" -d '{
"http": {
"properties": {
"client_location": {
"type": "string",
"fields": {
"geo": {
"type": "geo_point"
}
}
}
}
}
}'
And then you can access it in your queries using client_location.geo.
Also note that you have to re-index your data in order to populate that new sub-field... which means you might just as well delete your index and re-create it properly.
UPDATE
After installing Packetbeat you need to make sure to install the packetbeat template yourself as described here (i.e. it is not done automatically):
https://www.elastic.co/guide/en/beats/packetbeat/current/packetbeat-getting-started.html#packetbeat-template
curl -XPUT 'http://localhost:9200/_template/packetbeat' -d#/etc/packetbeat/packetbeat.template.json
