      loaded into collection default.scope1.collection1

      and having FTS index:

      I'm trying to run the following query:

      select count(*) from `default`.scope1.collection1 USE INDEX(USING FTS) where salary < -10 and salary > -100
      

      It returns an error:

      [
        {
          "code": 4000,
          "msg": "No index available on keyspace `default`:`default`.`scope1`.`collection1` that matches your query. Use CREATE PRIMARY INDEX ON `default`:`default`.`scope1`.`collection1` to create a primary index, or check that your expected index is online.",
          "query": "select count(*) from `default`.scope1.collection1 USE INDEX(USING FTS) where salary < -10 and salary > -100"
        }
      ]
      

      Almost the same query

      select count(*) from `default`.scope1.collection1 USE INDEX(USING FTS) where salary >-100 and salary < -10
      

      (I just changed positions of salary conditions)

      executes successfully
