pages pulled from cgi-bin redirected to home - help

hello im trying to use zoom search engine installed on cgi-bin of the same folder as my phpld directory - actually zoom it's supposed to search for pages not included in directory. but some how im unable to get it work... im lost and dont know what for should i look...
in this example when i try to search im allways redirected to my home page.
i have only usuall staff in my htacces (phpld uses) what im doing wrong please? should i add any thing to my htaccess?

any suggestions will be much apreciated

example url:
home:http://olca.biz
example search page:http://olca.biz/calle-albacete.htm
searched word:http://olca.biz/cgi-bin/search.cgi?zoom_query=almendros
(i dont understand why this url is redirected to my home instead showing result page)

this example domain is an addon domain, hosted on linux, apache version 1.3.41
