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.
