7 – 8 hook_search_info()

Define a custom search type.

This hook allows a module to tell search.module that it wishes to perform searches on content it defines (custom node types, users, or comments for example) when a site search is performed.

In order for the search to do anything, your module must also implement hook_search_execute(), which is called when someone requests a search on your module's type of content. If you want to have your content indexed in the standard search index, your module should also implement hook_update_index(). If your search type has settings, you can implement hook_search_admin() to add them to the search settings page. You can also alter the display of your module's search results by implementing hook_search_page(). You can use hook_form_FORM_ID_alter(), with FORM_ID set to 'search', to add fields to the search form (see node_form_search_form_alter() for an example). You can use hook_search_access() to limit access to searching, and hook_search_page() to override how search results are displayed.

Return value

Array with optional keys:

  • 'title': Title for the tab on the search page for this module. Defaults to the module name if not given.
  • 'path': Path component after 'search/' for searching with this module. Defaults to the module name if not given.
  • 'conditions_callback': Name of a callback function that 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. Sample callback function: sample_search_conditions_callback().
