Thanks Tamanjit and Erick. I tried out the filters, most of the usecases work except "q=bestbuy". As mentioned by Erick, that is a hard one to crack.
I am looking into DictionaryCompoundWordTokenFilterFactory but compound words like these: http://www.manythings.org/vocabulary/lists/a/words.php?f=compound_words and generic english words, it won't cover my need of custom compound words of store names like BestBuy, WalMart or CirtuitCity.
