Phrase Search and Slop

match_phrase checks whether analyzed terms occur in order. The class form is still available as the equivalent internal TypeScript API.

Exact phrase

{
  "query": {
    "match_phrase": {
      "body": {
        "query": "vector search"
      }
    }
  }
}

Equivalent internal TypeScript API:

import { MatchPhrase } from "@tryformation/querylight-ts";

const exact = new MatchPhrase({ field: "body", text: "vector search" });

Phrase with slop

Slop allows nearby terms to count even when there is a little distance between them.

{
  "query": {
    "match_phrase": {
      "body": {
        "query": "portable json index state",
        "slop": 2,
        "boost": 2
      }
    }
  }
}

Good queries to try in the demo

  • "portable json index state"
  • "vector search"
  • "phrase search"
