(Excellent)
   
My solution is based on a MySQL database and three major components:

* spider (traverses all documents for a site)
* indexer (creates / updates the index)
* query interface (for parsing queries and displaying results)

The spider and indexer would be developed in Perl, while the query interface could be built in Perl or Java, depending on your needs.

Should the spider be site friendly (obey robots.txt) and should only HTML pages be downloaded for indexing?

Should the indexer look at text only, or should META keywords be used as well? What about stop words, embedded punctuation (e.g. 'short-term' , 'VAX/VMS') and morphology ('interesting', 'interests', 'interested',...).

I assume that you want a web interface for the query interface. I will produce a basic design for this if no design guidelines exist.

I have (as you can see from my resume) previously developed a free text indexer and query interface for a large news database.

I would develop on Linux, but could test on windows as well, if needed. My bid of $120 is based on the above questions being answered. I will need about a week from start to finish.

Hope to hear from you.
