Uwe Schindler created LUCENE-6177:
-------------------------------------
Summary: Add CustomAnalyzer - a builder that creates Analyzers
from the factory classes
Key: LUCENE-6177
URL: https://issues.apache.org/jira/browse/LUCENE-6177
Project: Lucene - Core
Issue Type: New Feature
Components: modules/analysis
Reporter: Uwe Schindler
Assignee: Uwe Schindler
Fix For: 5.0, Trunk
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", key1, value1, key2, value2)
.addTokenFilter("standard")
.addTokenFilter("lowercase").
.addTokenFilter("stop", "ignoreCase", "true", "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).
