Uwe Schindler resolved LUCENE-6177.
-----------------------------------
Resolution: Fixed
I committed this now to get it into the coming Lucene 5.0. This is a really new
"feature" so it should get its major version. It is also quite "separate", so
there is no risk.
In the future we should use this in Solr (replace TokenizerChain / SolrAnalyzer
class). We may alo define our default Analyzers throughout the analysis-common
package with this class. I will open separate issues for that.
> Add CustomAnalyzer - a builder that creates Analyzers from the factory classes

> 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:
> {code:java}
> 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();
> {code}
> 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).
