# Overview

  a future version. Please use the [v2 API](/) where possible.

Compound queries combine multiple other queries. For instance, the following query looks for documents containing either the term `running` or `shoes` and boosts the relevance of documents matching `shoes`.

<CodeGroup>
  ```sql Function Syntax theme={null}
  SELECT description, rating, category
  FROM mock_items
  WHERE id @@@ paradedb.boolean(
      should => ARRAY[
          paradedb.boost(query => paradedb.term('description', 'shoes'), factor => 2.0),
          paradedb.term('description', 'running')
      ]
  );
  ```

  ```sql JSON Syntax theme={null}
  SELECT description, rating, category
  FROM mock_items
  WHERE id @@@
  '{
      "boolean": {
          "should": [
              {"boost": {"query": {"term": {"field": "description", "value": "shoes"}}, "factor": 2.0}},
              {"term": {"field": "description", "value": "running"}}
          ]
      }
  }'::jsonb;
  ```

Compound query functions are composable, which allows for arbitrarily fine-grained queries.
