Hi,
   
  Can anyone please tell as to what is the difference between PrefixFilter and 
WildcardQuery as far as memory is concerned? 
   
  I saw the code of PrefixFilter and it gets TermEnum for all the terms in the 
index. Won't this consume memory??
   
  I started using PrefixFilter, ConstantScoreQuery instead of WildcardQuery to 
avoid OOM exception. I am using ChainedFilters to do boolean logic for the 
filters.
   
  Thanks again for all the help.
