Hi!

I have way better results with DoubleMetaphone. It's available in apache
commons codec.

Indeed, although testing for 100 different contexts of the letter 'C' alone
sounds quite heavy.
 

You need a two step approach:

First select the canidates with phonetic keys (Soundex/DoubleMetaphone)
Then filter all canidates with the original search value with something like
JaroWinkler and a defined threshold.

But the "soundslike" operator in Drools is a binary relational operator. I
cannot relate your two-step approach to that. Drools currently has no
intent of exposing the word-to-key algorithm. But who knows - if there's
good cause...
