I was wondering if aliasing was supported for tokenizers and  
filters ?  
If not is there any plan to support it ?

The idea is that my automated annotation based tool automagically  
creates analyzers, tokenizers and filter definitions.  
If it encounters a definition that was previously sent to server it  
tries to create an alias for it rather than redefining the exact same  
analyzer.

That works fine for analyzers but it seems tokenizers and filters dont  
have that feature.

Thanks for your feedback.

Alexandre

Aliases, as you noted, are only supported for analyzers, not for tokenizers  
or token filters...
