Thread:Project:Support desk/Titles of my MediaWiki in Google search results

Hello. My MediaWiki is at http://pizmonet.co.il/. I'm using MediaWiki 1.19.0, PHP 5.2.17 and SQLite 3.3.7.

For some reason, when pages from my site appear in Google search results, their title contains the words "עמוד ראשי" (meaning "main page" in Hebrew). You can see an example here. I'm really confused as to why this is happening, as this is not a part of the page title in the actual site. I didn't find any place where I can change that.

If anyone knows how to change this text (or, preferably, remove those two words altogether), I'd be very grateful. Thanks in advance.
