52130 Repair Search Script

One of my fully working search (and spider) script at www.iftitah.com. Apart from spidering sites and creating database (title, description, url, keywords) from the spidered sites, the script has the ability to make a search query from the database. I found two major problems with the script: (a) The search query only queries keywords but not the title, description and url. I want the script to query all of it. (b) When querying keywords it can only query a single keyword, not a set of keywords. E.g. if a particular site contain the following keywords: "web, development, internet, search" the script can only query "web" or "development" or "internet" or "search" but NOT "internet development" or "web development" or "web search" or other type of combinations. Thus if a user make a search by typing "internet search" the script will display a zero results. Please read my further message and discuss it on the PMB.
