Sometimes during an ongoing search we receive an IndexReaderClosedException & found that it happens when a merge is completed.
We are on an older version of lucene (4.6.1). IndexFileDeleter (KeepOnlyLastCommitDeletionPolicy) deletes the file after the merge completes but we have an open IndexSearcher at that time. We verified that IndexReader has refCount > 0 but IFD blindly issues a delete. Anything we are doing wrong? Any help is much appreciated -- Ravi *stackTraceStr:org.apache.lucene.store.AlreadyClosedException: this IndexReader cannot be used anymore as one of its child readers was closed* at org.apache.lucene.index.IndexReader.ensureOpen(IndexReader.java:257) at org.apache.lucene.index.FilterAtomicReader.fields(FilterAtomicReader.java:380) at org.apache.blur.index.ExitableReader$ExitableFilterAtomicReader.fields(ExitableReader.java:81) at org.apache.lucene.search.TermCollectingRewrite.collectTerms(TermCollectingRewrite.java:52) at org.apache.lucene.search.ConstantScoreAutoRewrite.rewrite(ConstantScoreAutoRewrite.java:95) at org.apache.lucene.search.MultiTermQuery$ConstantScoreAutoRewrite.rewrite(MultiTermQuery.java:220) at org.apache.lucene.search.MultiTermQuery.rewrite(MultiTermQuery.java:288) at org.apache.lucene.search.BooleanQuery.rewrite(BooleanQuery.java:412)
