You’re going to need to tokenize to look up words, so a TokenFilter is a better place to put this sort of thing, I think.
Build off of Lucene’s SynonymFilter (and corresponding SynonymFilterFactory) https://github.com/apache/lucene-solr/blob/5e5fd662575105de88d8514b426bccdcb4c76948/lucene/analysis/common/src/java/org/apache/lucene/analysis/synonym/SynonymFilter.java <https://github.com/apache/lucene-solr/blob/5e5fd662575105de88d8514b426bccdcb4c76948/lucene/analysis/common/src/java/org/apache/lucene/analysis/synonym/SynonymFilter.java> I’m not sure exactly what your code is trying to do (please share that as well, for best assistance), but I do not recommend putting custom code into Solr’s package namespaces (and obviously that has issues here, because of the separate JAR and visibility/access).
