Hi, it's much easier to create own analyzers since Lucene 5.0 (without defining your own classes): https://lucene.apache.org/core/5_2_1/analyzers-common/org/apache/lucene/analysis/custom/CustomAnalyzer.html Using the builder you can create your own analyzer just with a few lines of code. The names and params used are the factories known from Apache Solr.
Analyzers are final by design.
