Welcome to the Apache Solr project!

Solr is the popular, blazing fast open source enterprise search platform
from the Apache Lucene project.

For a complete description of the Solr project, team composition, source
code repositories, and other details, please see the Solr web site at

Getting Started

See the "example" directory for an example Solr setup.  A tutorial
using the example setup can be found at
or linked from "docs/index.html" in a binary distribution.
Also, there are Solr clients for many programming languages, see

Files included in an Apache Solr binary distribution

  A self-contained example Solr instance, complete with a sample
  configuration and documents to index.
  Please see example/README.txt for information about running this

  The Apache Solr libraries.  To compile Apache Solr Plugins,
  one or more of these will be required.  The core library is
  required at a minimum. (see
  for more information).

Instructions for Building Apache Solr from Source

1. Download the Java SE 7 JDK (Java Development Kit) or later from
   You will need the JDK installed, and the $JAVA_HOME/bin (Windows: %JAVA_HOME%\bin) 
   folder included on your command path. To test this, issue a "java -version" command 
   from your shell (command prompt) and verify that the Java version is 1.7 or later.

2. Download the Apache Ant binary distribution (1.8.2+) from  You will need Ant installed and the $ANT_HOME/bin (Windows: 
   %ANT_HOME%\bin) folder included on your command path. To test this, issue a 
   "ant -version" command from your shell (command prompt) and verify that Ant is 

   You will also need to install Apache Ivy binary distribution (2.2.0) from and place ivy-2.2.0.jar file in ~/.ant/lib -- if you skip 
   this step, the Solr build system will offer to do it for you.

3. Download the Apache Solr distribution, linked from the above web site. 
   Unzip the distribution to a folder of your choice, e.g. C:\solr or ~/solr
   Alternately, you can obtain a copy of the latest Apache Solr source code
   directly from the Subversion repository:

4. Navigate to the "solr" folder and issue an "ant" command to see the available options
   for building, testing, and packaging Solr.
   To see Solr in action, you may want to use the "ant example" command to build
   and package Solr into the example/webapps directory. See also example/README.txt.

Export control
This distribution includes cryptographic software.  The country in
which you currently reside may have restrictions on the import,
possession, use, and/or re-export to another country, of
encryption software.  BEFORE using any encryption software, please
check your country's laws, regulations and policies concerning the
import, possession, or use, and re-export of encryption software, to
see if this is permitted.  See <> for more

The U.S. Government Department of Commerce, Bureau of Industry and
Security (BIS), has classified this software as Export Commodity
Control Number (ECCN) 5D002.C.1, which includes information security
software using or performing cryptographic functions with asymmetric
algorithms.  The form and manner of this Apache Software Foundation
distribution makes it eligible for export under the License Exception
ENC Technology Software Unrestricted (TSU) exception (see the BIS
Export Administration Regulations, Section 740.13) for both object
code and source code.

    Apache Solr uses the Apache Tika which uses the Bouncy Castle generic encryption libraries for
    extracting text content and metadata from encrypted PDF files.
