elasticsearchHow can I use the multi_match query in Elasticsearch?
The multi_match query in Elasticsearch allows you to search for multiple fields in a single query. It works by combining the query terms with OR operators. It also has the capability to boost certain fields or query terms.
Example of multi_match query code:
GET /_search
{
"query": {
"multi_match" : {
"query": "quick brown fox",
"fields": [ "title^5", "content" ]
}
}
}
Output example
{
"took": 3,
"timed_out": false,
"_shards": {
"total": 5,
"successful": 5,
"skipped": 0,
"failed": 0
},
"hits": {
"total": {
"value": 2,
"relation": "eq"
},
"max_score": 0.5753642,
"hits": [
{
"_index": "test",
"_type": "_doc",
"_id": "1",
"_score": 0.5753642,
"_source": {
"title": "The quick brown fox",
"content": "The quick brown fox jumps over the lazy dog"
}
},
{
"_index": "test",
"_type": "_doc",
"_id": "2",
"_score": 0.2876821,
"_source": {
"title": "The quick brown fox jumps",
"content": "The quick brown fox jumps over the lazy dog"
}
}
]
}
}
