7 – 8 hook_search_execute($keys = NULL, $conditions = NULL)

Execute a search for a set of key words.

Use database API with the 'PagerDefault' query extension to perform your search.

If your module uses hook_update_index() and search_index() to index its items, use table 'search_index' aliased to 'i' as the main table in your query, with the 'SearchQuery' extension. You can join to your module's table using the 'i.sid' field, which will contain the $sid values you provided to search_index(). Add the main keywords to the query by using method searchExpression(). The functions search_expression_extract() and search_expression_insert() may also be helpful for adding custom search parameters to the search expression.

See node_search_execute() for an example of a module that uses the search index, and user_search_execute() for an example that doesn't use the search index.

Parameters

$keys The search keywords as entered by the user.

$conditions An optional array of additional conditions, such as filters.

Return value

An array of search results. To use the default search result display, each item should have the following keys':

  • 'link': Required. The URL of the found item.
  • 'type': The type of item (such as the content type).
  • 'title': Required. The name of the item.
  • 'user': The author of the item.
  • 'date': A timestamp when the item was last modified.
  • 'extra': An array of optional extra information items.
  • 'snippet': An excerpt or preview to show with the result (can be generated with search_excerpt()).
  • 'language': Language code for the item (usually two characters).
