I suspect you have to do some fancy indexing. That is, index the following terms: sponge bob square pants spongebob squarepants.
But this requires that you understand all the variations you want to hit on ahead of time. Or, you could conceivably deal with wildcard queries, but I think this is the same problem as indexing the many different terms. Note that "Lucene in Action" has a section on indexing synonyms that could be very helpful to you if you decide to index several terms, particularly if you want span queries to operate in this space.
