Please note that you can use opposite case characters in the letter combinations if you need to break up the combination in two separate letters (Zh, zH, Ch, cH, Wx, wX, Eq, eQ, Ju, jU, Ja, jA). Be advised, though, that your search will most likely result in no entries found, unless such entries are added in the future. Also, this dictionary uses J (capital i short) instead of ^ (hard sign) in many words. Therefore, if you can't find a word with a hard sign in it, try typing i short in place of a hard sign.
