RangeQuery Over Lexical Fields

range compares string terms lexically. That works best when values are already sortable as strings.

Example

{
  "query": {
    "bool": {
      "filter": [
        {
          "range": {
            "order": {
              "gte": "03",
              "lte": "07"
            }
          }
        }
      ]
    }
  }
}

Equivalent internal TypeScript API:

import { BoolQuery, RangeQuery } from "@tryformation/querylight-ts";

const query = new BoolQuery({
  filter: [new RangeQuery({ field: "order", range: { gte: "03", lte: "07" } })]
});

Practical note

If you want numeric-style ordering, store values as zero-padded strings such as 01, 02, and 10.
