Vista - Search site database as well as pdf/html

I have placed a search form on the home page (using ASP/VbScript).
I want that when the user clicks search button, the script should search the
key word in the asp output pages (which display database results and not asp
code text) as well as in the searchable index of pdf files, html files
present on the site. The results shown should be concatenated with no
boundary segregation indicating that particular occurance is in database or
in pdf file.

Please help
