After installing icontent, my search feature started acting irratic, generally not returning results it should have found.

I went to the advanced search page, trying to isolate the problem. At the advanced search page, checking only icontent to be searched, with php debug turned on, I got a fatal error message in the debug.

The fatal error message said there was a call to an undefined function in icontent/include/search.inc.php at line 22 that is related to hidden directory.

I then went into search.inc.php, and commmented out line 22. All of my search functions are now working fine, to include searching in icontent.

My question is whether commenting out line 22 will cause any quirks in my search results ? And if so, is there a patch ?

Thanks
