I am implementing full-text search on my database via Legacy indexing.
I managed to create a Lucene index store by using apoc.index.addAllNodes, and I am also able to search through the index using apoc.index.search. I am using Neo4j 3.4.6 Enterprise edition. In the conf I added these lines:
However, a few minutes after starting the Neo4j instance I am not able to use the apoc.index.search function anymore. In the browser I receive the error function below.
First, I checked whether my database is still consistent using neo4j-admin check-consistency, and it is. Then I thought that maybe the RAM-memory was not enough to get everything working. So to be safe, I set the heapsize and pagecache size in the Conf in such a way that more than enough RAM-memory was available for other applications. Unfortunately this is also not the fix for this issue.
Does somebody has an idea what could possibly be the problem for the spontaneous closing of the Index Reader and how this closing can be prevented?
Thanks you in advance.
