Elasticsearch multi term filter
I'm quite new to Elasticsearch, so here's my question. I wanna do a search query with elasticsearch and wanna filter with multiple terms.
If I want to search for a user 'tom', then I would like to have all the matches where the user 'isActive = 1', 'isPrivate = 0' and 'isOwner = 1'.
Here's my search query
"query":{
"filtered": {
"query": {
"query_string": {
"query":"*tom*",
"default_operator": "OR",
"fields": ["username"]
}
},
"filter": {
"term": {
"isActive": "1",
"isPrivate": "0",
"isOwner": "1"
}
}
}
}
When I use 2 terms, it works like a charm, but when i use 3 terms it doesn't.
Thanks for the help!!
Solution 1:
You should use bool filter
to AND
all your terms:
"query":{
"filtered": {
"query": {
"query_string": {
"query":"*tom*",
"default_operator": "OR",
"fields": ["username"]
}
},
"filter": {
"bool" : {
"must" : [
{"term" : { "isActive" : "1" } },
{"term" : { "isPrivate" : "0" } },
{"term" : { "isOwner" : "1" } }
]
}
}
}
}
For version 2.x+ you can use bool
query instead of filtered
query with some simple replacement: https://www.elastic.co/guide/en/elasticsearch/reference/7.4/query-dsl-filtered-query.html
Solution 2:
As one of the comments says, the syntax has changed in recent ES versions. If you are using Elasticsearch 6.+, and you want to use a wildcard and a sequence of terms in your query (such as in the question), you can use something like this:
GET your_index/_search
{
"query": {
"bool": {
"must": [
{
"wildcard": {
"your_field_name_1": {
"value": "tom*"
}
}
},
{
"term": {
"your_field_name_2": {
"value": "US"
}
}
},
{
"term": {
"your_field_name_3": {
"value": "Michigan"
}
}
},
{
"term": {
"your_field_name_4": {
"value": "0"
}
}
}
]
}
}
}
Also, from the documentation about wildcard queries:
Note that this query can be slow, as it needs to iterate over many terms. In order to prevent extremely slow wildcard queries, a wildcard term should not start with one of the wildcards * or ?.
I hope this helps.
