I've run into the same problem vis a vis searching for T+A (and variants) on the forum.
@noromance Thanks. I think this was the OP's point, which I wanted to recognize and support.
I realize what the search engine is doing. My work around has been to input the T+A model number (the number part, e.g. 3100) rather than the letters.
I also realize it's a one off...however, given it is a brand name that has listings and dealers on Audiogon, site support could set a 'hard' / 'fixed' tag that would offer better search results.
