ignore special characters like -
 

When someone searches for the keyphrase 'word1 word2' , but in the site it is written as 'word1-word2' then no results are found.

How can I have the '-' ignored in order to have searches for 'word1 word2' also return results like 'word1-word2' ?

I think I already solved it.

I added '-: ' to the end of $phpdig_string_subst['iso-8859-1'] in config.php. Is this the correct way?

EDIT: This doesn't work, as it converts the space to a - character, I would like to have both 'word1 word2' and 'word1-word2' to show up in the results.

Perhaps try adding a - to the very end of the last character class in every instance of the $stop_regs variable definitions is the search_function.php file. Let me know how it works.

Thank you replying Charter.

I tried what you suggested and added a - to the end of stop_regs string (twice)

$stop_regs = "[][(){}[:blank:]=&?!&#%\$£*@+%:;,/\.'\"]-";


Unfortunately this didn't work. The number of results are the same. The only thing that changed was results' descriptions.

Charter, any other ideas for me to try?
