Not really, I've checked various queries in the same theme and the
results are repeatable. Searching for "nikon n" just returns
everyhting related to nikon "nikon f" on the other hand works as
expected and vice versa "ford f" and "ford n".

I'll try and create a new database containing only 2 items "volvo v90"
and "volvo s60" as far as I understand searching for "volvo v" should
return one result and "volvo" two.
