Hi.
I need help with exact search. In some cases I need to search phrase includes word, in some cases I need to find documents where field value matches exactly search query.
For example, I have this documents:
{"match_all": {}}
"hits": [{"_id": "0", "_index": "test_index", "_score": 1.0, "_source": {"fields": {"target": "VALUE"}, "some_key": "value"}, "_type": "_doc"},
{"_id": "1", "_index": "test_index", "_score": 1.0, "_source": {"fields": {"target": "TEST VALUE"}, "some_key": "value"}, "_type": "_doc"},
{"_id": "2", "_index": "test_index", "_score": 1.0, "_source": {"fields": {"target": "VALUE"}, "some_key": "value"}, "_type": "_doc"},
{"_id": "3", "_index": "test_index", "_score": 1.0, "_source": {"fields": {"target": "VALUE TEST"}, "some_key": "value"}, "_type": "_doc"},
{"_id": "4", "_index": "test_index", "_score": 1.0, "_source": {"fields": {"target": "VALUE SOME"}, "some_key": "value"}, "_type": "_doc"}],
"max_score": 1.0,
"total": {"relation": "eq", "value": 5}
I need to filter documents where fields.target matches only "VALUE" (2 of 5 documents).
How can I do that?
The preferable method is query_string, but if it is not possible, other types ok too.
Mapping:
{
"test_index": {
"mappings": {
"properties": {
"fields": {"properties": {"target": {"fields": {"keyword": {"ignore_above": 256, "type": "keyword"}}, "type": "text"}}},
"some_key": {"fields": {"keyword": {"ignore_above": 256, "type": "keyword"}}, "type": "text"}}
}
}
}
}
