Solr Core Reload URL

You can build your Solr Core Reload URL very easily.

For example:


eg. http://localhost:8983/solr/admin/cores?action=RELOAD&core=newcore

Hint: Reloading Solr Core

Sometimes, you might need to manually reload the Solr Core to see the Products you’ve committed manually to the Solr Index.

Newer version of Plugin will have feature to support two Solr Core, one additional core specially for performing indexing operation to bring further performance benefits.

Solr Incremental Data Import (IDI) Batch Size

This batch size depends on your application server resources and traffic you have on your site. This process is resource intensive and will consume almost 40-60% of CPU depending on your server configurations. We suggest keeping it between 100 to 500 and experiment to find the best value.

Once, these values are defined, click on Save and Restart Application to make changes. You can now proceed to next step of Performing Full Indexing.

Hint: Understanding Solr IDI Process Batch Size

As you already know we need to add products into Solr index before Solr can be used for performing queries. For a smaller site, this operation is easy & doesn’t take more than few minutes. But for an e-commerce store with large catalog size this operation could take quite some time before all of the products are being indexed by Solr.

To make it easy and reliable, the Solr Core plugin sends the products for indexing in certain batch size. Once one batch finishes, another starts. And so on all products will be indexed by Solr. Solr Core plugin keeps track of what products are already indexed and what products are pending. Once all products are indexed, the process stops.

Solr Core plugin also tracks products that are edited, deleted or newly added and refreshes the Solr index at set interval. Currently it is managed by a nopCommerce Scheduled Task. If the number of products changed are more than configured batch size then the IDI process will run multiple times until all changed products are indexed by Solr.
