Elasticsearch中具有匹配短语前缀的“ OR”过滤器

Question

I would like to do an Elasticsearch query wherein i want to do an OR filter

imagine i have this kind of documents

[ {name : "John Doe"}, {name :"Jane Doe"}, {name:"Steve Doe"} ]

A query that does the same thing with this SQL Query

SELECT * from table WHERE name LIKE 'Ja%' OR name LIKE 'Jo%'

Right now i'm using elasticsearch's match_phrase_prefix for the LIKE but i'm quite stuck with the OR.

Thanks

You can use bool should query for implementing the OR operation. You can actually make use of prefix query instead of match_phrase_prefix for what you've described. Anyways, if you still find use case for a match_phrase_prefix query just replace the prefix query in the request below with match_phrase_prefix query.

{
  "query": {
    "bool": {
      "should": [
        {
          "prefix": {
            "name": {
              "value": "ja"
            }
          }
        },
        {
          "prefix": {
            "name": {
              "value": "jo"
            }
          }
        }
      ]
    }
  }
}
