Some questions related to different topics in ES:

How can I define mappings for a type using Java API e.g. twitter?

Is there a way to see how a user supplied phrase is analyzed which  
will be useful for debugging? e.g. if the analyzer is custom, keyword  
tokenizer and edgeNGram filter, can I supply a query and inspect the  
generated terms?

Lucene has EnglishMinimalStemFilterFactory filter. Is this available  
in ES?

Thanks,  
Nishant

It is available via client.admin.indices  
Check AnalyzeActionTests.java or ScriptFieldSearchTests.java for some  
examples. Generally, you can check usages of  
IndicesAdminClient.java#putMapping  
or IndicesAdminClient.java#preparePutMapping in elasticsearch source code.
