you said site, I assume you mean forum posts? our search only looks in forum posts…
not sure on that particular string, though I could guess… generally, anything I searched for on your site I found except for that string… obviously cvn500 wont match when there is a – in the actual string…
but your mysql set up, like most default to, is limited to 4 character minimum searches… anything less wont match… which means you cannot search for cvn or 500… only way to change that is for you or your host to change the mysql configuration file my.cnf on your your server – we cannot affect that…
why its not matching? I can only guess that the – (dash) in the word is throwing mysql off somehow… and the string on either side is only 3 characters and thus too short to search for… the dash might be a mysql match special character – will need to research that… if so, perhaps it can be escaped to be a real character…
