org.apache.lucene.analysis.boost.DelimitedBoostTokenFilter

All Implemented Interfaces:: Closeable, AutoCloseable, Unwrappable<TokenStream>

public final class DelimitedBoostTokenFilter extends TokenFilter

Characters before the delimiter are the "token", those after are the boost.

For example, if the delimiter is '|', then for the string "foo|0.7", foo is the token and 0.7 is the boost.

Note make sure your Tokenizer doesn't split on the delimiter, or this won't work
