…and has been for 8 years.
I came across MySQL bug #2095 today:
full-text search for words containing hyphens won't work Submitted: 11 Dec 2003 6:15 Hyphen '-' characters break literals at the moment. A search for something like "GATA-D22S690" finds all entries containing GATA and not the full hyphenated text.
MySQL disputes the fact that this is a bug.
But in reality — as the submitters points out — there are many cases where hyphens are part of words. The example I ran into tonight was product model numbers (eg. “00−17″ or “j-35″).
The MySQL docs recommend recompiling or modifying one of two system files. None of these options are feasible in a shared hosting environment.
I can’t believe this bug exists. As far as I’m concerned this is a complete and utter deal breaker for any application that needs to search non-word strings containing hyphens. I’ve been exclusively using MySQL for my entire career and I now know that a bunch of sites I’ve worked on in the past 10 years were launched with this bug.
