Hi. A cool aspect of GNU/GPL software is that users get the source code free so they can change it to fit their individual needs. If you want to remove all or some of the ._~@#$:&%/;,=- characters, just do the following and then reindex.

In search_function find and modify the following as desired:

$what_query_chars = "[^".$phpdig_words_chars[PHPDIG_ENCODING]." \\'.\_~@#$:&\%/;,=-]+";

In phpdig_functions.php find and modify the following as desired:

$text = ereg_replace('[^'.$phpdig_words_chars[$encoding].' \\'._~@#$:&%/;,=-]+',' ',$text);

In robot_functions.php find and modify the following as desired:

if (strlen($key) > SMALL_WORDS_SIZE and strlen($key) <= MAX_WORDS_SIZE and !isset($common_words[$key]) and ereg('^['.$phpdig_words_chars[PHPDIG_ENCODING].'#$]',$key))
