Allow search for terms which include non-letter symbols, like plus (+), hyphen (-), period (.), colon (:), etc.

When you search for words in Confluence that contain characters which are not letters, these are stripped out by the tokeniser when performing a search.

This means such searches sometimes do not return any results or return results that do not really match the search criteria.

Some example searches that don't work properly:

• C++
• MySQL 4.x
• 5.3.7
• MPEG-LA
