How to Make Partial Word Searches the Default

By default, Postbox looks for exact matches when searching.  For example, a search on drag will not find hits with drags, dragon.  To manually do a wild cards search, append an asterisk to your query.  For example, drag* will find hits on drag, drags, dragon, etc. 

To make partial word searches the default:

  • Open Config Editor.
  • Enter mail.search.auto_prefix into the "Filter" textbox.
  • Double-click on mail.search.auto_prefix to change the value from false to true.

Note: only trailing asterisks are valid and that search performance may degrade for users with lots of messages when this hidden pref is enabled.
