弹性搜索中的多“匹配短语”查询

Question

this should be obvious to me but is not. The following two-match only the second phase (in this case, Cape Basin )

"query": {
  "match_phrase": {
    "contents": {
      "query": "St Peter Fm",
      "query": "Cape Basin"
    }
  }
}

"query": {
  "match_phrase": {
    "contents": {
      "query": ["St Peter Fm", "Cape Basin"]
    }
  }
}

while the following croaks with an error

"query": {
  "match_phrase": {
    "contents": {
      "query": "St Peter Fm"
    },
    "contents": {
      "query": "Cape Basin"
    }
  }
}

I want to match all documents that contain either phrases exactly as entered.

Answer 1

Your first query is not really a valid JSON object because you use the same field name twice.

You can use a bool must query to match both phrases:

PUT phrase/doc/1
{
  "text": "St Peter Fm some other text Cape Basin"
}
GET phrase/_search
{
  "query": {
    "bool": {
      "must": [
         {"match_phrase": {"text":  "St Peter Fm"}},
         {"match_phrase": {"text":  "Cape Basin"}}
      ]
    }
 }
}

Answer 2

It turns out you can do this by enabling phrase semantics for multi_match .

To do this you add a type: attribute to the multi_match syntax as below:

GET /_search
{
  "query": {
    "multi_match" : {
      "query":      "quick brown fox",
      "type":       "phrase",
      "fields":     [ "subject", "message" ]
    }
  }
}

Once you think of it that way (vs. enabling "multi" support on other search clauses) it fits in where you'd expect.
