Introduction

The search module adds the ability to search for content by keywords. Search is often the only practical way to find content on a large site, and is useful for finding both users and posts.

To provide keyword searching, the search engine maintains an index of words found in your site's content. To build and maintain this index, a correctly configured cron maintenance task is required. Indexing behavior can be adjusted using the search settings page; for example, the Number of items to index per cron run sets the maximum number of items indexed in each pass of a cron maintenance task. If necessary, reduce this number to prevent timeouts and memory errors when indexing.
