(i can decide to display only 10 results per page) Either use something like htdig or Lucene or run a cron that crawls your files as you indicate above and caches the content to a MySQL (or other db server) FULLTEXT column. Then query/search accordingly. You can feel free to re-invent this particular wheel... but you'll probably spend a lot of time doing it wrong.
