Probably when you drop a lot of content in Alfresco using the Lucene subsystem, Alfresco try to store each content In-Transaction this behavior will cause a lot of fragmentation of the index and sometimes can bring issues during the indexing process.

Have you tried to execute a full reindex?

In this way Alfresco rebuild the index in a batch way without fragmentation. This is a typical procedure to correctly maintain your index.

Try to put the following property for reindexing all your contents from scratch:

index.recovery.mode=FULL

Then restart Alfresco and look at the alfresco.log to see the progress of the reindexing process.

When Alfresco starts correctly, if you don't want to execute a Full reindex the next time that you restart Alfresco, set the property to the previous value:

index.recovery.mode =AUTO

Hope this helps.

Thank you for suggestion, but full reindex is not resolution for us. At least because we have very big database and reindex will take about 3 days.

Also I want to guarantee that node can be found at least after 24 hours after creation.

At this point I have found some workaround, may be someone will find it useful... I made some scheduler that searches last transactions and checks if they were indexed, if not reindex, hope it will work.

I use

nodeDAO.getTxnsByCommitTimeDescending(fromTimeInclusive, toTimeExclusive, count, null, false); to find transactions

and

abstractReindexComponent.isTxnPresentInIndex(Transaction txn); to search if it was indexed

Always opened for better resolution.
