Shalin Shekhar Mangar 259bc2baf7 SOLR-12607: Fixed two separate bugs in shard splits which can cause data loss. The first case is when using TLOG replicas only, the updates forwarded from parent shard leader to the sub-shard leader are written only in tlog and not the index. If this happens after the buffered updates have been replayed then the updates can never be executed even though they remain the transaction log. The second case is when synchronously forwarding updates to sub-shard leader fails and the underlying errors are not propagated to the client 2018-08-02 08:24:32 +05:30

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
