Hi,

I recently integrated search in hibernate project. I am having some issue.

I am calling method:


Earlier it worked fine, but once it gave an exception for purging issue- "Unable to purge all from Lucene index: foo.bar.User". It keeps repeating this exception for different entities. After that I tried many things but it does not seem to work. I tried deleting the index folder and run the indexer again but didnt work. I tried setting purging to false to avoid the exception as per the code below (along with it added some optimization that would help solve the issue as per one website.):



But it still gives the same exception. My environment is Linux. The search jar versions are:

hibernate3.jar
hibernate-search-3.4.0.Final.jar
hibernate-jpa-2.0-api-1.0.0.Final.jar
lucene-core-3.1.0.jar.

Could you please help me understand how to resolve this issue?

Hi, this sounds very much like - viewtopic.php?f=9&t=1013098
Can you create a full test case so that we can reproduce the problem?

The issue is this is not surely reproducible case. Yesterday when I tried writing a test case for it to post it here and ran it, it ran perfectly. Deleted all the indexes and recreated them. Now the entire app is working fine!

I am lucky this time. But still living in fear when it might return.

Hi,
it looks like normal usage of indexing was attempted while the MassIndexer was running. your application should prevent that, for example by showing a "in maintenance" webpage while reindexing is happening.

Hibernate Search 4.x can use the MassIndexer while normal activity happens.
