[jira] [Commented] (SOLR-8347) Asynchronous searcher for custom
component
[ https://issues.apache.org/jira/browse/SOLR-8347?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=15037809#comment-15037809 ]
Upayavira commented on SOLR-8347:
---------------------------------
[~bogandy] I'd suggest you ask this question on the Solr user list. This does not strike me, at present, as a bug in Solr. It most certainly isn't a blocker for the project. If, after discussion on the Solr user list, you find an enhancement to Solr that would help, or find a specific bug, that would be the time to open a ticket here.

> 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.
