Spell Checker

Hi We need to check the spelling of a word which is actually a Domain name. For example we have to check the word "onlinetradeing". When checked with the spell checkers we are getting the words which are unrelated such as on, obliterating, incinerating, intruding etc. But exactly what we want was "online trading". So we would like to have the word to be split into phrases and check the spelling too. The normal spell checkers are just checking the words in the dictionary but not splitting the word into phrases.
