If we were only so lucky... it uses its own scopus algorithm and compiles
the results into a single binary database/file.

two words.... deaf ears!
One that starts with 'V' comes to mind.
I actually had in mind IIS Index server (what the hell...Its free..) but I
would consider a higher quality product that might start with a 'V'.
The product states it is a "Case Base Reasoning search engine" and the core
engine comes from a French company (if you want, I will send you specific
company names). Currently the front end is JSP pages, but because of the
32-bit dll's the application cannot run on Unix (now that's brilliant
architecture!). It has to be a Windows NT server running a web server that
supports JSP (like Apache or Jakarta). We are paying the company to rewrite
the front end in ASP, because we have to pass personalization information
between 4 other apps, one is a TCL-based proprietary XML search engine, the
other ASP, another an ActiveX application, all of which have to pass
WebMethods user values between each app. Did I mention that the IIS web
servers are reverse-proxied with Tivoli's Policy Director using WebMethod
personalization data? ( I seen a lot of WebMethod swag around here
lately.... its making me paranoid.)
Now that I actually write it all down, I am thinking... My god, we're
idiots!
Its a mess. For some reason the project manager has locked down the project
plan from me, and has not sent me a summary of his schedule after I
requested it. Hummmm..... This is one of many applications I have been
tasked with to shine a light on.
