OK, I see. So, in your code, "reader" is the top-level reader, not the one segment you are pulling a scorer on (context.reader()). So you are building your cache on the top-level reader, not the segment's reader? Is that intentional? (It's not NRT friendly). But, yes, your ReaderClosedListener will be called once that top-level reader is closed, and that will then evict its entries from the cache. > I saw that > FieldCacheImpl is using a CoreClosedListener, whereas I am using a > ReaderClosedListener. What is the difference between these two? A single segment's core readers (that read the postings, stored fields, term vectors, etc.) are shared between multiple SegmentReader instances; each of those SegmentReader instances only changes in what documents are deleted. The core is closed only once all SegmentReaders that share that core have been closed. > I will surely look at the FBS replacement you have pointed out.
