Addon search via post???

[Sojik]

I don't know too much about web development but from what I understand,
WoWI uses a search method that doesn't use a URL. So you have to actually be on the website to search it instead of editing the URL. My browsers (iPhone and Desktop) allow custom search engines but I don't think I can add WoWI. Is switching to or supporting URL search (i.e. wowinterface/q?=<search_term> or something) even possible? Thanks.
