It does mention the following which might be what you're after:
Can search by all textual data about a product (Name, Short description, Full description, Meta keywords, Options, Features, Languages, Search words, Stop words, Product code, Meta description, Price, Time of creation, Status, Popularity , Product code for combinations of options, Vendor name).
I have bought and started using Cart power's Live search - the customer service was not so good - The license to the add on did not work and I was unable to login to the help desk eventually I got through to the sales team who fixed the license.
The good news is that it was easy to install and works much better than the default CS cart search.
I went through the settings quickly and will go through them again slowly as I was not able to index the site on my first try; not sure why - maybe it just takes a long time - or maybe I left out a step?
In summary the add on was good enough that I will revisit their website to look at their other addons.
I am new to social media (although I have two teenagers, so I have expert consults on staff...) I am considering an add-on that allows customers to login from Facebox etc.
A kety question is whether it is a good idea to have customers login from a third website? I really don't know.
