[hibernate-issues] [Hibernate-JIRA] Commented: (HSEARCH-222) Entities not found during concurrent update

Entities not found during concurrent update ------------------------------------------- Key: HSEARCH-222 URL: http://opensource.atlassian.com/projects/hibernate/browse/HSEARCH-222 Project: Hibernate Search Issue Type: Bug Components: directory provider, engine Reporter: Sanne Grinovero Fix For: 3.1.0.Beta2 As we update an entity by deleting it from index by using an IndexReader, and afterwards we reinsert it using an IndexWriter, there is a point in time in the middle were no DPlock is held on the Directory, At this moment a ReaderProvider could (re)open the index and all searches performed on this IndexReader will not find the entity at all. We should use a Read/Write Lock on DP instead of the current ReentrantLock to use a write lock during index updates and avoid creating a bottleneck for different threads needing a searcher.
