I did change 2 other lines:

       $search_condition[] = "node.avail = 'Y'";

to

       $search_condition[] = "(node.avail = 'Y' OR node.avail = 'H')";

and ...

 $search_condition[] = "c.avail = 'Y'";

to

 $search_condition[] = "(c.avail = 'Y' OR c.avail = 'H')";

Those might of made it work as well.
