This seems incredibly inefficient. I can think of three ways to do this:

  1. Each time you want to perform a search, open each text file, one by one, search if the word exists in that file, and then spit out the files that matched.
  2. Create a database (e.g. MySQL) in advance of all the words in each text file. Update the database based on how often the text files may change. Each time you want to perform a search, simply query the database for which text files match the word(s) being searched for.
  3. Use a third-party search indexer such as Sphinx or Lucene.
