Complex Queries and Boolean Operations
Query String Parameters
This section introduces key fields such as q for the query, s for the starting result, and p for the number of results per page. The following query string parameters can be passed to the API to customize how the results are displayed:
| Parameter | Description | Required | Default Value |
|---|---|---|---|
q | The query to be performed by the API. Supports various filters. | yes | |
s | Return results starting at the number specified. | no | 1 |
p | Number of results to return in the request. (See section Pagination and Limits for more details.) | no | 10 |
api_key | The key identifying your application. | yes |
If the p parameter is not included, 10 results will be returned by default. If the s parameter is omitted, the results will start from the first entry. The q parameter offers flexible options, allowing you to build complex queries.
