function callback_search_conditions in Drupal 7

Provide search query conditions.

Callback for hook_search_info().

This callback is invoked by search_view() to get an array of additional search conditions to pass to search_data(). For example, a search module may get additional keywords, filters, or modifiers for the search from the query string.

This example pulls additional search keywords out of the $_REQUEST variable, (i.e. from the query string of the request). The conditions may also be generated internally - for example based on a module's settings.

Parameters

$keys: The search keywords string.

Return value

An array of additional conditions, such as filters.
