  3. NoSQL Database
    • No relational databases; designed for massive data volumes.
  4. Admin Interface
    • Demo of the admin interface planned for future videos.
  5. Flexible and Extensible
    • Can extend Java classes for customization.

Basic Concepts and Terminology

  • Searching Methods:
    1. Manual page search.
    2. Use of index (similar to book index).

Terminology Explained

  • Search Term: What you are searching for.
  • Queries: How you construct the search.
  • Indexes: Created for documents; similar to an index page of a book.
  • Documents: Hold data with fields (like rows/columns in SQL).
  • Index Writer: Writes indexes created from data.
  • Search Index: Where searches are performed.

Solr Cloud

  • Provides high availability and fault tolerance.
  • High Availability: System operates continuously without failing.
  • Fault Tolerance: System returns to a safe condition after failure.
  • Data Organization: Data organized into shards across multiple machines.
  • Zookeeper: Manages indexing and search requests; serves as a load balancer.

Solr Cloud Architecture

  • Zookeeper Cluster: Handles indexing and search requests; manages cluster.
  • Shards: Logical partitions of a collection; one acts as a leader.
  • Nodes: Each instance of Solr is referred to as a node.
  • Collections: Groups of cores representing an index.

Configuration Files in Solr

  1. solr.xml: Contains Solr cloud-related information.
  2. solrconfig.xml: Core-specific configurations for requests and indexing.
  3. schema.xml: Defines fields and types within a schema.
  4. core.properties: Contains core-specific configurations.
