Tommaso Teofili commented on LUCENE-3731:
-----------------------------------------
Hi Robert,
reusing the CAS is good, as you note in the patch we need to take care of how
to let each tokenizer instance get its own AE, in the previous Solr version
core names were used to cache and get AEs.
As said on dev@ we may start with letting each tokenizer have its own AE and
then improve the design once concurrency is fixed.
I'm doing tests with other types of UIMA Flow controllers, right now the
WhiteboardFlowController seems to behave slightly better.
> Create a analysis/uima module for UIMA based tokenizers/analyzers

> As discussed in SOLR-3013 the UIMA Tokenizers/Analyzer should be refactored
> out in a separate module (modules/analysis/uima) as they can be used in plain
> Lucene. Then the solr/contrib/uima will contain only the related factories.
