Hi Robert, Thanks for the reply.
My Actual Usecase is to Highlight the First occurence of the search word in the sentence it occured. In my case,I do not have access to original documents . Iam looking for optimum way by which i need to reduce the index disk space. I tried SimpleHighlighter and FastVectorHighlighter both of which increases index space considerably since i need to use Store.yes while indexing. I read PostingsHighlighter uses compression while storing and it may help reducing index space. Has anyone tried using PostingsHighlighter ? Also is there some other effecient compression techniques i can apply so that it reduces disk space and also not increase the search time.
