Open source or Yahoo! BOSS based web search engine

Project that I imagine will? utilize? technologies such as? YAHOO! Boss API, something like dotnet or dundass charting, mysql, PHP, AJAX, ASP.net, etc Objective is to create free search engine that is the pulse? for investors,? to monitor what investors and companies are saying real-time,? with graphical trending, in two areas, social media, i.e. yahoo! finance message boards, etc and SEC filings.? ? User should be able to enter search term(s) and then on next page view graphical results in user defined time period. Example of user request would be how many times the word "recession" was used between March 1st and March 8th from social media or SEC filings. Then I would like user to be able to call up stock charts on general market or specific stock from some free online source so they can see any relationship /trends between the two charts and possibly predict future market moves and identify trends based on word usage prevalence. Finally would like to query databases to see what terms are being most used and push this out as 'top ten' type list on home page Here is The search engine for yahoo finance message boards, click 'advanced search' on the link below to get to it: <[login to view URL]> The SEC advanced engine is here, you need to then click 'advanced search' . <[login to view URL]> I know from SEC web site you can set up daily FTP dump so may need to can store this in a database and access from there.
