keyword search help

hello sir, we are creating a cdrom database in postgresql wherein we have cd rom titlename,author,year etc and keywords as fields. we will store a set of keywords for each record. i want to know how to enter those keywords in to database (whether to have comma between keywords or plain) and code to search for keywords. i.e. if i enter a keyword then it should search for that keyword in keyword field and display result. keywords are strings an there will also be some combinational search. i believe u will see to this and do the needful. thanking you with rgds Arun ____________________________________________________________________ Get free e-mail and a permanent address at http://www.amexmail.com/?A=1
