AND
I need to search type is Permanent or GUEST condition this is array of fields(OR) statement
AND
I need to search Location is NY(&) condition
test = [{'id':1,'name': 'A','subject': ['Maths','Accounting'],'type':'Contract', 'Location':'NY'},
{ 'id':2,'name': 'AB','subject': ['Physics','Engineering'],'type':'Permanent','Location':'NY'},
{'id':3,'name': 'ABC','subject': ['Maths','Engineering'],'type':'Permanent','Location':'NY'},
{'id':4,'name':'ABCD','subject': ['Physics','Engineering'],'type':['Contract','Guest'],'Location':'NY'}]
Query is below,3rd one got it, How to add 1 and 2
content_search = es.search(index="professor", body={
"query": {
"bool": {
"must": {
"match_all": {}
},
"filter": [
{
"term": {
"Location.keyword": "NY"
}
}
]
}
}
})
content_search ['hits']['hits']
Expected out is id [{ 'id':2,'name': 'AB','subject': ['Physics','Engineering'],'type':'Permanent','Location':'NY'},{'id':4,'name':'ABCD','subject': ['Physics','Engineering'],'type':['Contract','Guest'],'Location':'NY'}]

Answer 1

The filter clause (query) must appear in matching documents. However
unlike must the score of the query will be ignored. Filter clauses are
executed in filter context, meaning that scoring is ignored and
clauses are considered for caching.
Please go through this Elasticsearch documentation on bool queries, to get a detailed understanding about it.
Adding a working example with index data(same as that in question), search query, and search result
Search Query:
{
"query": {
"bool": {
"must": {
"match": {
"Location.keyword": "NY"
}
},
"filter": [
{
"bool": {
"should": [
{
"match": {
"subject.keyword": "Accounting"
}
},
{
"match": {
"subject.keyword": "Physics"
}
}
]
}
},
{
"bool": {
"should": [
{
"match": {
"type.keyword": "Permanent"
}
},
{
"match": {
"type.keyword": "Guest"
}
}
]
}
}
]
}
}
}
Search Result:
"hits": [
{
"_index": "stof_64370980",
"_type": "_doc",
"_id": "2",
"_score": 0.10536051,
"_source": {
"id": 2,
"name": "AB",
"subject": [
"Physics",
"Engineering"
],
"type": "Permanent",
"Location": "NY"
}
},
{
"_index": "stof_64370980",
"_type": "_doc",
"_id": "4",
"_score": 0.10536051,
"_source": {
"id": 4,
"name": "ABCD",
"subject": [
"Physics",
"Engineering"
],
"type": [
"Contract",
"Guest"
],
"Location": "NY"
}
}
]
Another Search Query:
You can even use terms query that returns documents that contain
one or more exact terms in a provided field.The terms query is the
same as the term query, except you can search for multiple values.
{
"query": {
"bool": {
"must": [
{
"terms": {
"subject.keyword": [
"Physics",
"Accounting"
]
}
},
{
"terms": {
"type.keyword": [
"Guest",
"Permanent"
]
}
},
{
"match": {
"Location.keyword": "NY"
}
}
]
}
}
}
Update 1:
{
"query": {
"bool": {
"must": [
{
"terms": {
"subject.keyword": [
"Physics",
"Accounting"
]
}
},
{
"terms": {
"type.keyword": [
"Guest",
"Permanent"
]
}
},
{
"match": {
"Location.keyword": "NY"
}
},
{
"query_string": {
"query": "ABCD"
}
}
]
}
}
}
