Tim Underwood 5202a713ba Java 9+ GC Logging filesize parameter should be 20M instead of 20000 
JEP 158 (https://openjdk.java.net/jeps/158) says the filesize parameter is the “file size in kb” however that appears to not be the case since when it is set to a value of 20000 you end up with GC logs that are only 20000 bytes in length.  Setting the value to 20M produces the desired result of GC log files that are 20MB in size.

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
