content creation topic forum but search

Hi

Create content using a CMS and hikashop is for let end user buy product. So buyer need a good way to find our product and google search engine do a really outstanding work without to be tied to a specific webser or CMS .
It seem content type in joomla ( article categories links) could be name object type in programing language . An other way to disturb undertanding of concept ... like Microsoft .

I browse some commercial web site and find very usefull website that have many fields base on carateristic of the specification of an object we want to find see .
for memory card www.ldlc.com/informatique/peripherique-p...281/+fv368-1276.html
for appartment www.pap.fr/annonce/locations

Does this can be achieve using hikashop ?
Does the implementation is base on catalog ?
Could i have more information about search is working in hikashop and if general extension are by default compatible with Hikashop specific field / object type like product ?
