This document provides an introduction to using Solr for search. It discusses using Solr to search for products by name and other fields using SQL-like queries. It also covers configuring Solr schemas, including field types, filters, and analyzers. The document demonstrates how to define Solr cores and indexes, and explains how to add and update documents. Finally, it provides additional resources for learning more about Solr caching, replication, spell checking and tools for integrating Solr.
