Subject RE: Searching across spaces

You might consider using overlapping bi-gram tokenization with stripped out whitespace and
a PhraseQuery.

So your tokenized content, "spongebob squarepants", would look like:

sp po on ng ge eb bo ob bs sq qu ua ar re ep pa an nt ts

and your tokens for your query, "sponge bob", would look like

sp po on ng ge eb bo ob

Add each token to the PhraseQuery and you should match.

This is very similar to the techniques used for searching in Asian languages which do not
seperate words with spaces. There are probably some side effects for compound words that you
didn't mean to do this too, but without knowing the exact domain of compound words that you
wish to support, this is probably the best you will be able to do.

Subject: Searching across spaces


How can I search accross spaces in the document when the spaces aren't present in the search.
For example, if the document contains "spongebob squarepants" but the user searches on "sponge
bob" I would like to get the result.
