Common issues

edit

When constructing search API requests, some common issues are:

The query parameter is omitted.
The value of query is not a string or a number.
The value of page is not a JSON object.
The value of page.size is not greater than or equal to 1 and less than or equal to 1000.
The value of page.current is not greater than or equal to 1 and less than or equal to 100.
The query requests more than 10000 results, returning an empty response.

The following sections have moved:

Performing a single search query → Search API

Performing a multiple search query → Multi search API

Before you search → Request body

Page → Request body, Response body

Limit on results per query → Request body, Response body

Performing a single search query with Lucene query syntax → Examples
