Setting enabled to true Elasticsearch

I'm new to elasticsearch. I have an index type as follows
{
"myindex" : {
"mappings" : {
"systemChanges" : {
"_all" : {
"enabled" : false
},
"properties" : {
"autoChange" : {
"type" : "boolean"
},
"changed" : {
"type" : "object",
"enabled" : false
},
"created" : {
"type" : "date",
"format" : "strict_date_optional_time||epoch_millis"
}
}
}
}
}
}
I'm unable to fetch the details having changed.new = completed. After some research i have found that it's because the changed field is set to enabled : false. and I need to change the same. I tried as follows
curl -X PUT "localhost:9200/myindex/" -H 'Content-Type: application/json' -d' {
"mappings": {
"systemChanges" : {
"properties" : {
"changed" : {
"enabled" : true
}
}
}
}
}'
But I'm getting error as following.
{"error":{"root_cause":[{"type":"index_already_exists_exception","reason":"already exists","index":"myindex"}],"type":"index_already_exists_exception","reason":"already exists","index":"myindex"},"status":400}
How can I change the enabled to true in order to fetch the details of the changed.new field?
you are trying to add an index again with the same name and hence the error.
See the below link for updating a mapping
https://www.elastic.co/guide/en/elasticsearch/reference/current/indices-put-mapping.html
The enabled setting can be updated on existing fields using the PUT mapping API.

Elasticsearch does not found an existing document using a the DSL

I dont know why, using the URI Search way to search a document is returning the right document, but the document is not found if I use the API DSL.
To reproduce the issue:
Without any index created, I insert this document:
curl http://localhost:9299/integrationtest-index/searchable/ID_XXXX2 -d '{ "ref" : "XXXX2", "field1" : "value1" }'
So the index is created automatically with the default mapping (type searchable):
curl http://localhost:9299/integrationtest-index?pretty
{
"integrationtest-index" : {
"aliases" : { },
"mappings" : {
"searchable" : {
"properties" : {
"field1" : {
"type" : "string"
},
"ref" : {
"type" : "string"
}
}
}
},
"settings" : {
"index" : {
"field1" : "value1",
"ref" : "XXXX2",
"number_of_shards" : "5",
"creation_date" : "1466780216631",
"number_of_replicas" : "1",
"uuid" : "GBj2VF-wQy6JP74AqoIn5g",
"version" : {
"created" : "2020099"
}
}
},
"warmers" : { }
}
}
This query return one document:
curl http://localhost:9299/integrationtest-index/searchable/_search?q=ref:XXXX2
But this other query response that does not exist:
curl -XPOST http://localhost:9299/integrationtest-index/searchable/_search/exists -d '
{
"query": {
"term" : {
"ref" : "XXXX2"
}
}
}'
Why the last query said that the document does not exist?
Environment:
ElasticSearch 2.2.0
Ubuntu 16.04 LTS
OpenJDK Runtime Environment (build 1.8.0_91-8u91-b14-0ubuntu4~16.04.1-b14)
I have the same problem every few months, so I decided response myself and share my stupids errors.
By default, elasticsearch use index:analyzed, so the query with term does not found any document.
If you use the URI Search way, elasticsearch is executing a query_string and not a term query.
This query is working:
curl -XPOST http://localhost:9299/integrationtest-index/searchable/_search/exists -d '
{
"query": {
"match" : {
"ref" : "XXXX2"
}
}
}'
More information in the documentation, in the section Why doesn’t the term query match my document?

Elastic search csv river module not working

I am trying to index csv file in elasticsearch
curl -XPUT localhost:9200/_river/my_csv_river/_meta -d '
{
"type" : "csv",
"csv_file" : {
"folder" : "/tmp",
"filename_pattern" : ".*\\.csv$",
"first_line_is_header" : "true",
"field_separator" : ",",
"field_id" : "_id"
},
"index" : {
"index" : "my_csv_data_1",
"type" : "csv_type_1",
"bulk_size" : 100,
"bulk_threshold" : 10
}
}'
after indexing while searching http://localhost:9200/my_csv_data_1/_search
got
{
error: "IndexMissingException[[my_csv_data_1] missing]",
status: 404
}
any thoughts or i missed any thing?

Specify Routing on Index Alias's Term Lookup Filter

I am using Logstash, ElasticSearch and Kibana to allow multiple users to log in and view the log data they have forwarded. I have created index aliases for each user. These restrict their results to contain only their own data.
I'd like to assign users to groups, and allow users to view data for the computers in their group. I created a parent-child relationship between the groups and the users, and I created a term lookup filter on the alias.
My problem is, I receive a RoutingMissingException when I try to apply the alias.
Is there a way to specify the routing for the term lookup filter? How can I lookup terms on a parent document?
I posted the mapping and alias below, but a full gist recreation is available at this link.
curl -XPUT 'http://localhost:9200/accesscontrol/' -d '{
"mappings" : {
"group" : {
"properties" : {
"name" : { "type" : "string" },
"hosts" : { "type" : "string" }
}
},
"user" : {
"_parent" : { "type" : "group" },
"_routing" : { "required" : true, "path" : "group_id" },
"properties" : {
"name" : { "type" : "string" },
"group_id" : { "type" : "string" }
}
}
}
}'
# Create the logstash alias for cvializ
curl -XPOST 'http://localhost:9200/_aliases' -d '
{
"actions" : [
{ "remove" : { "index" : "logstash-2014.04.25", "alias" : "cvializ-logstash-2014.04.25" } },
{
"add" : {
"index" : "logstash-2014.04.25",
"alias" : "cvializ-logstash-2014.04.25",
"routing" : "intern",
"filter": {
"terms" : {
"host" : {
"index" : "accesscontrol",
"type" : "user",
"id" : "cvializ",
"path" : "group.hosts"
},
"_cache_key" : "cvializ_hosts"
}
}
}
}
]
}'
In attempting to find a workaround for this error, I submitted a bug to the ElasticSearch team, and received an answer from them. It was a bug in ElasticSearch where the filter is applied before the dynamic mapping, causing some erroneous output. I've included their workaround below:
PUT /accesscontrol/group/admin
{
"name" : "admin",
"hosts" : ["computer1","computer2","computer3"]
}
PUT /_template/admin_group
{
"template" : "logstash-*",
"aliases" : {
"template-admin-{index}" : {
"filter" : {
"terms" : {
"host" : {
"index" : "accesscontrol",
"type" : "group",
"id" : "admin",
"path" : "hosts"
}
}
}
}
},
"mappings": {
"example" : {
"properties": {
"host" : {
"type" : "string"
}
}
}
}
}
POST /logstash-2014.05.09/example/1
{
"message":"my sample data",
"#version":"1",
"#timestamp":"2014-05-09T16:25:45.613Z",
"type":"example",
"host":"computer1"
}
GET /template-admin-logstash-2014.05.09/_search

Elasticsearch not storing field, what am I doing wrong?

I have something like the following template in my Elasticsearch. I just want certain part of the data returned, so I turn the source off, and explicitly stated store for the fields I want.
{
"template_1" : {
"order" : 20,
"template" : "test*",
"settings" : { },
"mappings" : {
"_default_" : {
"_source" : {
"enabled" : false
}
},
"type_1" : {
"mydata" :
"store" : "yes",
"type" : "string"
}
}
}
}
}
However, when I query the data, I don't get the fields back. The query works, however, if I enable the _source field. I am just starting with Elasticsearch, so I am not quite sure what I am doing wrong. Any help would be appreciated.
Field definitions should be wrapped in properties section of your mapping:
"type_1" : {
"properties": {
"mydata" :
"store" : "yes",
"type" : "string"
}
}
}
