TrackerV3 is not the only app in the World which deals with files searching. I have used many of those applications and as I've noticed all of them use sign "&" for logical "AND" in search expressions. You see, it is not a question of my personal preferences, but there are some general conventions... If somebody uses some such programms simultanously (and I do use them), it is difficult to remember what language uses the cuurent program for the same things.
This could be optional for every user via "Configuration" menu to choose which symbol to use for "AND".

I did not use "&" because it can be part of a filename (contrary to "/") so you should be able to search for &. Can those other file searchers search for "&"??
This aside, i'm totally d'accord that common standards (hence expectations) should be met where possible.

Yes, the most of them can. They use for this purpose double sign (for searching "Proctor & Gamble" an user has to enter "Proctor && Gamble". Or something else, e.g. prefix "/" before the symbol "&" ("Proctor /& Gamble") when it is not a logical operator, but a part of filename to be searched.

You convinced me easily, and so i've done it: " & " is logical AND (previously "/"), " | " is logical OR (previously ";") , "\" is the escape character, so it's "Proctor \& Gamble" in TrackerV3.
