Stemming - How to add tokens and dont replace the existing tokens?

[Mark Schoy]

Hi,

I like to use the HunspellStemFilterFactory to improve my search results.
Why isn't there an arg "inject" like in solr.PhoneticFilterFactory to
add tokens instead of replacing them?

I don't want to replace them, because documents with the "unstemmed"
word should be more relevant.

Thanks.
