   >  But because the methods i can apply to Expression is limited,
   
   It's certainly planned to expand what you can express in the filters 
(basically all compute kernels should be possible). The functionality already 
exists in the C++ library, but needs to be exposed in Python. 
   
   > 1、So i think some bool simplify should support, such as :
   (ExpressionA or ExpressionB) and ExpressionA -> ExpressionA
   
   Functionality to simplify expressions is not exposed (but it will be done 
under the hood though, when passing such an expression as a filter). Feel free 
to open JIRA issues with very specific feature requests.
