Hi,

I am using the IndexQueryParserModule and in the plugin, I have my  
TermsFilter implementation.

By default, since I am writing my own ABCFilterBuilder/Parser, I believe, I  
can control the caching, and ES will, by default, not cache the Lucene  
TermsFilter that I return. Correct me if I am wrong.

Can I specify a cache\_key and have this explicitly cached by ES? It seems,  
from other FilterParsers, that this may be possible.

Although, when the documents in the filter condition change, I want the  
cache to be invalidated and a new filter created again, and then cached  
again.

Is that possible? Please let me know.

Thanks,  
Sandeep
