FUDforum 2.3 includes a full text search that allows users to search the posted messages by entering one or more keywords. The user has the option of limiting the search to a particular forum or category or they can search the entire forum. A user may either limit a search to a particular forum or category or search the entire forum.

The search form allows the user to specify whether to use the strict AND logic, which will find only the messages containing all of the specified keywords. Or to use the more relaxed OR logic, which will find any message that matches at least one of the specified terms in the query.

The search results can be sorted by date, allowing the user to specify whether the most recent messages should be shown first or last.
