Summary: Asynchronous searcher for custom component
Key: SOLR-8347
URL: https://issues.apache.org/jira/browse/SOLR-8347
Project: Solr
Issue Type: Bug
Components: SearchComponents - other
Reporter: Bogdan Marinescu
I'm trying to write a custom component for fuzzy searches.
After solr calls my component, I create a Thread and give it the
SolrIndexSearcher and some params.
Problem is after a few seconds I get an Exception that the indexreader was
closed
{code}

anymore as one of its child readers was closed

Is there a way of locking the IndexReader so it doesn't get closed by other
threads?
