extension for advanced search?

[alesandroca]

Hi all,
I am seeking for an extension, which does the "advanced search" for my website. My website is a ecommerce with Virtumeart 2.
Advanced search should be similar to ebay: you can find some products of that category, with these types, which cost less than x euros.
I sought in joomla extension (section "site search"), I found these interestings extensions: Universal AJAX Live Search, PixSearch Ajax Search module, RokAjaxSearch, AceSearch, Advanced Site Search, MijoSearch. But none does what I need :-(

Somebody could help me? Some ideas?

Thank you in advance.
Alessandro
