Apache project

Because the source code is freely Apache project, anyone can adapt the server for specific needs, and there is a large public library of Apache add-ons. For example, adding the following to the solrconfig. This framework will in future releases enable Solr to move shards around based on load, disk etc.

Added "param" query type to facet domain filter specification to obtain filters via query parameters Apache project facet command can be filtered using a new parameter filter.

I put it on a page and then a few months later when this project started, I pointed people to this page and said: TermsQuery performance boost by a more aggressive default query caching policy.

Disable graph query production via schema configuration. This resulted in some or most metrics not being reported via JMX after core reloads, depending on timing Creating a core.

Previous spatial classes have been moved to a new spatial-extras module. It also makes a cute pun on "a patchy web server" -- a server Apache project from a series of patches -- but this was not its origin.

Now possible to use IP fragments in replica placement rules. Solr is trying to start some cores twice. Fixed document accounting in IndexWriter. This includes numeric int, float, long, doubleInetAddress, BigInteger and binary range filtering, as well as geo-spatial shape search over indexed 2D LatLonPoints.

In built AuthorizationPlugin that provides fine grained control over implementing ACLs for various resources with permisssion rules which are stored in ZooKeeper. Expect it to be default in the next release. The query parser is much more versatile than the handler as it works in cloud mode as well as anywhere a normal query can be specified.

This enables better multi-word synonym support. Highlights of this Solr release include: A new configset management API has been added.

Manage massive amounts of data, fast, without losing sleep

Lucene can be downloaded from Apache project IndexWriter, used to add, update and delete documents in your index, will no longer accept broken token offsets sometimes produced by mis-behaving token filters. Until fixes are available, all Solr users are advised to restart their Solr instances with the system parameter -Ddisable.

It supports password authentication and digital certificate authentication. New set-trigger, remove-trigger, set-listener, remove-listener, suspend-trigger, resume-trigger APIs Auto-scaling: For example, one computer with one Apache installation could simultaneously serve www.

It just sort of connotated: Classic query parser no longer splits on whitespaces. Light term vectors can be used with offsets in postings for fast wildcard MultiTermQuery highlighting.

The PostingsHighlighter was removed. Substantial performance gains for delete and update heavy Lucene usage; see http: It can highlight phrases as accurately as the standard Highlighter. Fix a bug where Solr was attempting to load the same core twice Error message: Streaming Expressions adds a new statistical programming syntax for the statistical analysis of sql queries, random samples, time series and graph result sets.

Migrating to the UnifiedHighlighter should be straight-forward. The spatial module no longer depends on third-party libraries. Use metrics-jvm library to instrument jvm internals such as GC, memory usage and others. Fix for CVE which is a working 0-day exploit reported on the public mailing list.

The XML Parser will be fixed and the fixes will be included in the 7.

Welcome to Apache Lucene

CloneFieldUpdateProcessorFactory now supports choosing a "dest" field name based on a regex pattern and replacement init options. Virtual hosting allows one Apache installation to serve many different Web sites. IndexWriter metrics collection turned off by default, directory level metrics collection completely removed until a better design is found Fixed: DefaultSimilarityFactory has been removed, implicit default Similarity has been changed to SchemaSimilarityFactory, and SchemaSimilarityFactory has been modified to use BM25Similarity as the default for field types that do not explicitly declare a Similarity.

Both Apache Lucene and Solr 7. CommonGramsQueryFilter was producing a disconnected token graph, messing up phrase queries during query parsing Highlights of this Solr release include:This site is a catalog of Apache Software Foundation projects. It is designed to help you find specific projects that meet your interests and to gain a broader understanding of the wide variety of work currently underway in the Apache community.

There are Managed by the Apache Community Development Project. Loading data, please wait. The Apache Lucene Project Management Committee decided in a vote, that the Apache Lucene sub-project "Open Relevance" will be discontinued.

There was only modest activity during the last years and the project made no releases. The Apache HTTP Server Project is a collaborative software development effort aimed at creating a robust, commercial-grade, feature-rich and freely available source code implementation of an HTTP (Web) server.

"The Apache Software Foundation is a cornerstone of the modern Open Source software ecosystem – supporting some of the most widely used and important software solutions powering today's Internet economy.". The Apache Cassandra database is the right choice when you need scalability and high availability without compromising performance.

Linear scalability and proven fault-tolerance on commodity hardware or cloud infrastructure make it the perfect platform for mission-critical data. Cassandra's support for replicating across multiple datacenters is .
