 DokuWiki now uses an index to search even big wikis very fast, to be able to find anything the index needs to be filled with current data. Information about a page's content is added and updated when a page is viewed by a user. Each page includes an invisible image ([[wp>webbug]]) which calls the index update process if needed.((Note that the webbug is used for other tasks, too.  See http://forum.dokuwiki.org/post/3116))  (That is, if the timestamp of the page is newer than the timestamp of the index file.)
-The index consists of files called ''page.idx'', ''w//[n]//.idx'' and ''i//[n]//.idx'' located in the index directory. ''w//[n]//.idx'' contains a list of all words (except stopwords) with a length of //n// that appear on the wiki pages. For every line in ''w//[n]//.idx'' there is a line in the corresponding ''i//[n]//.idx'' file that contains page references in the form of ''pn*freq''. ''pn'' is a line number for ''page.idx'', ''freq'' denotes how often the word appears on the page. Multiple page references are separated with a colon.

-The [[indexer]] uses a language specific stopword file which contains a list of very common words which will never be indexed (e.g. the word ''the'' in English). Searching for such a word will not return any hits. This stopword file is located in language folder of the DokuWiki installation, that is <dokuwiki>/inc/lang/<language>/stopwords.txt so you can edit the file in proper folder for adding or removing words not indexed for that language.

 If you upgraded your wiki from an older version without an index, your search won't return anything until the index is built. You can either wait until this happens by browsing your wiki or install the [[plugin:searchindex]] plugin. You can also use the provided [[cli|commandline script]] for updating the index.
