Improving Search Speed

SOLR and Magento Relationship

04/10/2023 © 2011 Crown Partners. All Rights Reserved. 20

User submits a search query

Magento connects to SOLR and sends over query

SOLR processes query and returns Magento Product IDs

Magento loads the product IDs and displays them to the user

Is SOLR the Problem?

Check qtime of a query

– /select params={…} hits=79 status=0 QTime=48
