Apache Lucene and Solr
Apache Lucene is a high-performance, full featured text search engine library written in Java.
Apache Solr is an enterprise search platform written using Apache Lucene. Major features include full-text search, index replication and sharding, and result faceting and highlighting.
Online Documentation
This README file only contains basic setup instructions. For more comprehensive documentation, visit:
Building Lucene/Solr
(You do not need to do this if you downloaded a pre-built package.)
Lucene and Solr are built using Apache Ant. To build Lucene and Solr, run:
ant compile
If you see an error about Ivy missing while invoking Ant (e.g., .ant/lib does not exist
), run ant ivy-bootstrap
and retry.
Sometimes you may face issues with Ivy (e.g., an incompletely downloaded artifact). Cleaning up the Ivy cache and retrying is a workaround for most of such issues:
rm -rf ~/.ivy2/cache
The Solr server can then be packaged and prepared for startup by running the
following command from the solr/
directory:
ant server
Running Solr
After building Solr, the server can be started using
the bin/solr
control scripts. Solr can be run in either standalone or
distributed (SolrCloud mode).
To run Solr in standalone mode, run the following command from the solr/
directory:
bin/solr start
To run Solr in SolrCloud mode, run the following command from the solr/
directory:
bin/solr start -c
The bin/solr
control script allows heavy modification of the started Solr.
Common options are described in some detail in solr/README.txt. For an
exhaustive treatment of options, run bin/solr start -h
from the solr/
directory.
Development/IDEs
Ant can be used to generate project files compatible with most common IDEs. Run the ant command corresponding to your IDE of choice before attempting to import Lucene/Solr.
- Eclipse -
ant eclipse
- IntelliJ -
ant idea
- Netbeans -
ant netbeans
Running Tests
The standard test suite can be run with the command:
ant test
Like Solr itself, the test-running can be customized or tailored in a number or ways. For an exhaustive discussion of the options available, run:
ant test-help
