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. -Vasu
