The Query condition is used to match the query string. The Query condition has the following properties:

• context: The context of the condition. This must be set to query.
• match_type: The type of match to perform. This can be set to exact, prefix or contains.
• value: The value to match against.

Below is an example of the query condition which will apply the actions when the query has a prefix of "star".

{
  "search_settings": {
    "query_rules": [
      {
        "id": "1",
        "conditions": [
          [
            {
              "context": "query",
              "match_type": "prefix",
              "value": "star"
            }
          ]
        ],
        "actions": [
          // actions that will apply for conditions
        ]
      }
    ]
  }
}
