Search redirects to index

The problem was due to htaccess file that was in the root directory.

**`.htaccess`**

    DirectoryIndex start.php

This was causing all of the index.php files to be changed to start.php. This filr did not exist in my wordpress directory. When I renamed the index.php to start.php in the wordpress installed sub directory the search started to work.

I removed the DirectoryIndex command from the root directory and changed start.php to index.php. WordPress blog is now working correctly.
Thanks,
John
