The highlighting processor would need to account for complex searches like the above one.
Also, the regular expression search syntax used by MySQL and PHP differs quite a bit. This might cause problems since the search is performed using MySQL regex syntax while the highlighting would need to be performed using PHP regex syntax. However, since the MySQL regex syntax is mostly a subset of the PHP regex syntax, this may actually work out fine, but I'd need to do some testing.
Generally, I don't know how important this feature is. What do others think? Would you like to see highlighting of search results?
Tks a lots for your complete response.
I´m translating the REFBASE to Spanish!
I will send you the common.inc IN SPANISH VERSION! As soon I finished it!
Some text I am translating directly from the archive search.php because are not defined it as a variable in common.inc.
