Product Search software for ecommerce?

[skuba]

Hi,
Would you know what are the major players on the market providing search solutions for ecommerce sites?

I have used Atomz before, and I heard good things about Endeca. Do you know anything about Endeca or other major player?

Thanks a lot

Any suggestions here?

Endeca seems trustworthy,I have heard good reviews about it especially from eBusiness Group.
