title: custom search implementation
body: <p>I am new to web designing .. I am designing a video streaming website something like youtube. I have many videos and their details(in a separate xml file, which has fields like speaker, title etc.)
  I want to implement a custom search on the basis of their fields and i dont know how to. please help me out. 
  should i combine them to a mysql table or parse through multiple xml files, if so how to?
  p.s there are a lot of videos.
  (i don't want to use a google search or something like that .. i want to implement one)</p>
  
  <p>Thanks a lot. </p>
