Filter Full Text Search based on User ID - elasticsearch

Question

GET _search
{
"query": {
"match": {
"content": "this test"
}
}
}
This gave me below result:
{
"took" : 2,
"timed_out" : false,
"_shards" : {
"total" : 6,
"successful" : 6,
"skipped" : 0,
"failed" : 0
},
"hits" : {
"total" : 3,
"max_score" : 0.5753642,
"hits" : [
{
"_index" : "inbox",
"_type" : "mailbox",
"_id" : "6bb174ab-a4ce-4409-a626-c9a42c98b89e",
"_score" : 0.5753642,
"_source" : {
"user_id" : 13,
"content" : "This is a test"
}
},
{
"_index" : "inbox",
"_type" : "mailbox",
"_id" : "1304cf2e-a1d4-40ca-9876-9abb08c4474d",
"_score" : 0.36464313,
"_source" : {
"user_id" : 10,
"content" : "This is a test"
}
},
{
"_index" : "inbox",
"_type" : "mailbox",
"_id" : "623c093c-4408-445e-abb1-460d2c5004cd",
"_score" : 0.36464313,
"_source" : {
"user_id" : 15,
"content" : "This is a test"
}
}
]
}
}
Which is good. However, I need to filter them by user_id. I mean I need to score only specific user and their content.
GET _search
{
"query": {
"match": {
"content": "this test",
"user_id": 10
}
}
}
When I add user_id i get this error:
{
"error": {
"root_cause": [
{
"type": "parsing_exception",
"reason": "[match] query doesn't support multiple fields, found [content] and [user_id]",
"line": 5,
"col": 18
}
],
"type": "parsing_exception",
"reason": "[match] query doesn't support multiple fields, found [content] and [user_id]",
"line": 5,
"col": 18
},
"status": 400
}
Why? And How to properly filter based on user_id?

Answer 1

You can use term query to filter the result by user_id.
Update your query as below:
{
"query": {
"bool": {
"must": [
{
"match": {
"content": "this test"
}
}
],
"filter": [
{
"term": {
"user_id": 10
}
}
]
}
}
}

Answer 2

The query should be like this:
{
"query": {
"bool": {
"must": [
{
"match": {
"content": "this test"
}
},
{
"match": {
"user_id": 10
}
}
]
}
}
}

Answer 3

Use bool query to combine filters
{
"query": {
"bool": {
"must": [
{
"match": {
"content": "this is content"
}
},
{
"term": {
"user_id": {
"value": 47545
}
}
}
]
}
}
}
