Apache Solr Reference Guide
This reference guide describes Apache Solr, the open source solution for search. You can download Apache Solr from the Solr website at
.

This Guide contains the following sections:
Getting Started
: This section guides you through the installation and setup of Solr.
Using the Solr Administration User Interface
: This section introduces the Solr Web-based user interface. From your browser you can view
configuration files, submit queries, view logfile settings and Java environment settings, and monitor and control distributed configurations.
Documents, Fields, and Schema Design
: This section describes how Solr organizes its data for indexing. It explains how a Solr schema defines
the fields and field types which Solr uses to organize data within the document files it indexes.
Understanding Analyzers, Tokenizers, and Filters
: This section explains how Solr prepares text for indexing and searching. Analyzers parse
text and produce a stream of tokens, lexical units used for indexing and searching. Tokenizers break field data down into tokens. Filters perform
other transformational or selective work on token streams.
Indexing and Basic Data Operations
: This section describes the indexing process and basic index operations, such as commit, optimize, and
rollback.
Searching
: This section presents an overview of the search process in Solr. It describes the main components used in searches, including
request handlers, query parsers, and response writers. It lists the query parameters that can be passed to Solr, and it describes features such as
boosting and faceting, which can be used to fine-tune search results.
The Well-Configured Solr Instance
: This section discusses performance tuning for Solr. It begins with an overview of the
solrconfig.xml
file, then tells you how to configure cores with
, how to configure the Lucene index writer, and more.
solr.xml
Managing Solr
: This section discusses important topics for running and monitoring Solr. It describes running Solr in the Apache Tomcat servlet
runner and Web server. Other topics include how to back up a Solr instance, and how to run Solr with Java Management Extensions (JMX).
SolrCloud
: This section describes the newest and most exciting of Solr’s new features, SolrCloud, which provides comprehensive distributed
capabilities.
Legacy Scaling and Distribution
: This section tells you how to grow a Solr distribution by dividing a large index into sections called shards,
which are then distributed across multiple servers, or by replicating a single index across multiple services.
Client APIs
: This section tells you how to access Solr through various client APIs, including JavaScript, JSON, and Ruby.
