It’s an off-the shelf forum package and the minimum search word length is 4 characters. But dashes aren't seen as valid characters, so TLA-1 becomes TLA and 1, so nothing is found.
The easiest way around it is for Pit Bull to rename the kits with longer titles or getting rid of hyphens and making sure they are at least 4 characters long e.g. TLA-1 becoming PBTLA-1 or TLA1.
