Description

I prepared some "generic Analyzer class CustomAnalyzer, that makes it easy to build analyzers like in Solr or Elasticsearch. Under the hood it uses the factory classes. The class is made like a builder:

Analyzer ana = CustomAnalyzer.builder(Path.get("/path/to/config/dir"))
  .withTokenizer("standard")
  .addTokenFilter("standard")
  .addTokenFilter("lowercase")
  .addTokenFilter("stop", "ignoreCase", "false", "words", "stopwords.txt", "format", "wordset")
  .build();

It is possible to give the resource loader (used by stopwords and similar). By default it tries to load stuff from context classloader (without any class as reference so paths must be absolute - this is the behaviour ClasspathResourseLoader defaults to).

In addition you can give a Lucene MatchVersion, by default it would use Version.LATEST (once LUCENE-5900 is completely fixed).
