Undefined Variable: $reg
 

I think I found a typo in version 1.8.0:

When doing searches with keywords as short as SMALL_WORDS_SIZE or shorter, I would get this message from PHP for each keyword entered:

Notice: Undefined variable: reg in ..\libs\search_function.php on line 150

I notice that this array, '$reg' only exists in the code in 4 or 5 places, and never gets assigned any value. Is this a typo? should this be '$regs' instead of '$reg'? It also exists in robot_functions.php around line 150.

After changing all occurances to '$regs', the above error dissappeared.

Hi. Yes, the following line:
should be the following:
The "$reg" in the robot_functions.php file is fine.

awsome... thanks!
