SolrCloud is flexible distributed search and indexing, without a master node to allocate nodes, shards and replicas. Solr also provides a way to perform basic diagnostics for a collection using the healthcheck command: The healthcheck command gathers basic information about each replica in a collection, such as number of docs, current status (active, down, etc. Example (with directory structure) that adds a node to an example started with "bin/solr -e cloud": The previous command will start another Solr node on port 8987 with Solr home set to example/cloud/node3/solr.

However, after creating your collection, the schemaless functionality can be disabled in order to lock down the schema (so that documents indexed after doing so will not alter the schema) or to configure the schema by yourself. In this section you will learn how to start a SolrCloud cluster using startup scripts and a specific configset. To provide high availability and increase uptime, SOLR Cloud was considered as an option to provide high uptime on one of ARDC's primary functions. Context. This page provides a simple tutorial to start Solr in SolrCloud mode, so you can begin to get a sense for how shards interact with each other during indexing and when serving queries. Its major features include full-text search, hit highlighting, faceted search, real-time indexing, dynamic clustering, database integration, NoSQL features [1] and rich document (e.g., Word, PDF) handling. Next, the script will prompt you for the number of replicas to create for each shard. Solr is the popular, blazing-fast, open source enterprise search platform built on Apache Lucene™. The script starts by asking you how many Solr nodes you want to run in your local cluster, with the default being 2.
