If you want to search only the headers already on your hard drive, right-click the Refresh button.
It shouldn't delete whole cache files without a reason. Headers are normally deleted under just a few circumstances.
[LIST]
[*]The headers are older than the oldest on the server
[*]A cache file hasn't been updated after the number of days on the Newsgroups tab in the Settings
[*]Headers are older than the "Delete headers older than" option on the Server tab in the Settings
[/LIST]
