Digy, Some additional information from the discussion on the lucene-net-user list with Floyd Wu.
I ran some further tests using Java Lucene 2.3.2 and JDK 1.5. The Java equivalents of the two small test applications I use to inspect an index and compact it, function identically to the .NET versions (that were built with VS2005 and Lucene.NET 2.3.1). That Luke cannot open the index appears to be a problem within Luke. Even if Floyd's index contains some odd entries, Java Lucene 2.3.2 does not flag the index as corrupt; and both the Java and .NET versions report the same index content before and after the optimize operation. -- Neal ************************************************************** Neal Granroth Software Engineer, Molecular Spectroscopy Thermo Fisher Scientific 5225 Verona Road, Madison, WI 53711 neal.granr...@thermofisher.com Tel: 608-276-5645 Fax: 608-276-6328 www.thermofisher.com WORLDWIDE CONFIDENTIALITY NOTE: Dissemination, distribution or copying of this e-mail or the information herein by anyone other than the intended recipient, or an employee or agent of a system responsible for delivering the message to the intended recipient, is prohibited.

[ https://issues.apache.org/jira/browse/LUCENENET-169?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12697335#action_12697335 ] Digy commented on LUCENENET-169: -------------------------------- Although you can overcome all of them somehow; * controlling the the lifetime of IndexWriter/IndexReader in a naturally manner, * reopening the IndexReader only when needed using (for ex) FileSystemWatcher, * providing a separation between data & bussiness layer, * providing other apps an interface that may want to write its own user interface, * accessing a single search service from different web apps/from load balanced web servers * controlling the lifetime of searching/indexing code (without being effected by the restart of the IIS processes automatically when some memory limit is exceeded (for ex.) ) * Ability to access some system resources that can be restricted by IIS etc. make me think a separete search service is a better idea.But at last, it is a design decision of you.
