Trac has built-in search functionality to search for occurrences of keywords and substrings in wiki pages, tickets and changeset properties, such as author, revision and log messages.
In addition to the Search module, you will also find a small search field above the navigation bar. It provides convenient access to the search module from all pages.
The search results show the most recent modifications ranked first.
For quick access to project resources, the quick-search field at the top of every page can be used to enter a TracLink, which will take you directly to the resource identified by that link:
trunk directory in the default repository
trunk directory in the repos1 repository
To disable the Quickjump feature for a keyword start the query with an exclamation mark (!): use !TracGuide to search for occurrences of the literal word TracGuide.
From the Wiki, it is possible to link to a specific search using search: links:
search:?q=crash will search for the string "crash"
search:?q=trac+link&wiki=on will search for "trac" and "link" in wiki pages only
On the search page, pressing the modifier key while selecting a search filter will unselect all other search filters.
