Query Language

The integrated Query Language can be used to filter the result.

A full-text search and several Query prefixes are available, which can limit the result.

Most of these prefixes can be used for sorting.

By default the results are sorted by their relevance given the search query.


For a detailed explanation of the query parameter, see Query Language - Introduction.

For a collection of all available prefixes, look at Query Language - Prefixes.
