What Tokenizerfactory/TokenFilterFactory can/should I use so a search for "wal mart" matches "walmart"(quotes not included in search or index)?

[Christian Zambrano]

There are a lot of company names that people are uncertain as to the 
correct spelling. A few of examples are:
1. best buy, bestbuy
2. walmart, wal mart, wal-mart
3. Holiday Inn, HolidayInn
What Tokenizer Factory and/or TokenFilterFactory should I use so that 
somebody typing "wal mart"(quotes not included) will find "wal mart" and 
"walmart"(again, quotes not included)

Thanks,

Christian
