Domain specific search engine.
5. Input Screen: Accept input from user and parse the string extract keywords to search.
1. Inverted List Index:
This would be like a nightly process. Build a index database of all the keywords of the domain. Could restrict domain to one website like www.biology.edu. Have to use Inverted list index algorithms to build the index.
2. Store Index: The above built index has to be stored in a database or on a file. Sort it and keep it
ready for the search process to aquire results
3. Searching Index:
Keywords extractected in step 5 should be used to search the index and get pointers or links (
also stored in the database) to location of the webpage
4. Ranking Algorithm:
Can use Boolean, Vector or Probabalistic models to rank the results of the search process
6. Display Output:
After the ranking is done, the output has to be displayed best match first.

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.
