[hibernate-issues] [Hibernate-JIRA] Commented: (HSEARCH-274) Use Lucene's new readonly IndexReader

Use Lucene's new readonly IndexReader ------------------------------------- Key: HSEARCH-274 URL: http://opensource.atlassian.com/projects/hibernate/browse/HSEARCH-274 Project: Hibernate Search Issue Type: Improvement Components: directory provider, documentation Reporter: Sanne Grinovero Assignee: Emmanuel Bernard Fix For: 3.1.0.CR1 # LUCENE-1329: Add optional readOnly boolean when opening an IndexReader. A readOnly reader is not allowed to make changes (deletions, norms) to the index; in exchanged, the isDeleted method, often a bottleneck when searching with many threads, is not synchronized. The default for readOnly is still false, but in 3.0 the default will become true. (Jason Rutherglen via Mike McCandless) In addition we should wrap the returned IndexReader to contain needed information to close it without having to search it back in synchronized hashmaps.
