====== The indexer process ======

DokuWiki uses a background process triggered by a webbug to execute administrative tasks like building the [[search]] index, creating a [[sitemap]] or updating [[metadata]].

The indexer is located in ''lib/exe/indexer.php'' and is included as hidden image by the ''tpl_indexerWebBug()'' function.

For more info about the technique used see [[http://www.sitepoint.com/blogs/2005/11/03/web-bugs-for-job-scheduling-hack-or-solution/|Web bugs for job scheduling]]

===== Debugging =====

If you have problems with the indexer or the services it should provide, you can get some debugging output, by calling it directly and appending the parameter ''debug=1''.

Example: ''%%http://example.com/dokuwiki/lib/exe/indexer.php?id=start&debug=1%%''
