The Drupal search interface manages a global search mechanism.

Modules may plug into this system to provide searches of different types of data. Most of the system is handled by search.module, so this must be enabled for all of the search features to work.

There are three ways to interact with the search system:

  • Specifically for searching nodes, you can implement hook_nodeapi('update index') and hook_nodeapi('search result'). However, note that the search system already indexes all visible output of a node, i.e. everything displayed normally by hook_view() and hook_nodeapi('view'). This is usually sufficient. You should only use this mechanism if you want additional, non-visible data to be indexed.
  • Implement hook_search(). This will create a search tab for your module on the /search page with a simple keyword search form.
  • Implement hook_update_index(). This allows your module to use Drupal's HTML indexing mechanism for searching full text efficiently.

If your module needs to provide a more complicated search form, then you need to implement it yourself without hook_search(). In that case, you should define it as a local task (tab) under the /search page (e.g. /search/mymodule) so that users can easily find it.
