Force Solr to read from an updated index
I have a lucene index that i build and update using raw lucene indexers. I was wondering if there is a way to force solr to re-read the index without restarting the solr instance. Ive tried the update?commit=true but it doesnt seem to matter. The only way i can be sure solr -re-reads the index is by a total restart, whi开发者_C百科ch of course is not ideal in a production environment.
If you are using a multi-core setup, you can just reload that single core. AFAIK, while the core is being reloaded, the requests to that core are queued.
Not sure if there is another better way to do it. But I wrote this script to perform full or delta imports.
