[dba-VB] "Smart" fulltext search on large documents (data)base...

Hi All --

I have a task to implement a system providing "smart" fulltext search over a
large base of text documents.
My current plan is to use Google Docs.

I plan to get in the future 80 GB ($20.00 USD per year) hosted space on
GoogleDocs, put all the subject docs there, and then use Google API to
search via my documents base.

That seems to be it?

It should be even possible to create a simple (free?) Google Web Site as
front-end to that GoogleDocs documents base?

That GoogleDocs base/site is planned to be used by non-profit organization.

Am I missing something? 
Additional overhead costs to keep that solution's stuff on Google site?

And why I'm writing about that solution here in dba-VBA? - because I plan to
implement a front-end to that application system as an WinForms application
coomunicating with Windows API...

Thank you.
