I wish thunderbird had better search functionality.

For instance I can't specify that I am looking for mail either to or from a specific sender trough the search UI, only mails with an address as both to/from, which litters the results with mailing lists that have 100s of recipients.

Due to this, I often resort to zimbra for searching my mail box. The interface is much more effective.

Thunderbird does support this. You're using the "Search" box in the UI - use ctrl-shift-F to search in Mail and choose "match any of the following" in the UI and specify 2 rules - one for to, one for from. The Search from the main window's search box isn't that useful - the "find in mail" is much better.

Wow, this looks so much better, thank you. The search box isn't very usable, yet that's the only thing I discovered until now.

It doesn't help that, at least the French version, the menu entry for that function is cut (and looks like "search in m..."). "Advanced search" (the window title) sounds like a more descriptive and better title.

Yes the main search on the main window is rather useless by comparison. It provides far too much noise.
