Apache Lucene - Welcome to Apache Lucene. June 2. 01. 7 - Apache Lucene 6. Apache Solr 6. 6. Available. Fixed, and enhanced the generated query to not pollute the query.

Cache. Disable graph query production via schema configuration . This fixes broken queries for Shingle. Filter- containing query- time analyzers when request param sow=false. Fix indexed=. Index. Writer metrics collection turned off by default, directory level metrics collection completely removed (until a better design is found)Fixed: Transaction log replay can hit an Null.

Pointer. Exception due to new Metrics code. Fixed: Null. Pointer.

Exception in Cloud. Solr. Client when reading stale alias. Fixed: Unified. Highlighter and Postings.

Highlighter bug in Prefix. Query and Term. Range. Query for multi- byte text. See the Lucene CHANGES. Solr CHANGES. txt files included. February 2. 01. 7 - Apache Lucene 5. Apache Solr 5. 5.

Available. This saves between 6% memory for the largest types such an Inet. Address. Point to 3. Half. Float. Point.

This was another Xenserver install without Local Storage on the drive after the install completed. I installed new drives to both an HP 1RU server and an HP Blade server.

The BKD in- memory index for dimensional points now uses a compressed format, using substantially less RAM in some cases. The BKD writing now buffers each leaf block in heap before writing to disk, giving a small speedup in points- heavy use cases. This is caused by a bug introduced into the. Javadocs tool shipped with that update. The workaround was too late for this. Lucene release. Of course, you can use the binary artifacts. See the Lucene CHANGES.

Solr CHANGES. txt files included. November 2. 01. 6 - Apache Lucene 6. Apache Solr 6. 3. Available. It can highlight phrases as accurately as the standard Highlighter. Light term vectors can be used with offsets in postings for fast wildcard (Multi. Term. Query) highlighting. Simple. Query. Parser now parses '*' to Match.

All. Docs. Query. Fuzzy. Query now matches all terms within the specified edit distance, even if they are short terms. Points do not store the implicit split dimension in the 1- dimension case. This saves between 6% memory for the largest types such an Inet. Address. Point to 3.

Half. Float. Point. Many other changes and bug fixes. Highlights of this Solr release include. This is now fixed. Fix for the block. Unknown property which made inter- node communication impossible.

Support SOLR. Use 'wt=xlsx' request parameter on a query request to enable. See the Lucene CHANGES. Solr CHANGES. txt files included. September 2. 01. 6 - Apache Lucene 6.

Apache Solr 6. 2. Available. It's also now possible to create streaming expressions with the Solr Admin UI.

Fixed the ENUM faceting method to not be unnecessarily rewritten to FCS, which was causing slowdowns. Reduced garbage creation when creating cache entries. New . Previous spatial classes have been moved to a new spatial- extras module. Spatial. 4j has been updated to a new 0. Terms. Query performance boost by a more aggressive default query caching policy. Index. Searcher's default Similarity is now changed to BM2. Similarity. Easier method of defining custom Char.

Tokenizer instances. Highlights of this Solr release include. The output has less details and is not backward compatible. Users should set use. Doc. Values. As. Stored=. BC dates are now better supported since they are now formatted with a leading '- '.

AD years after 9. Parse exceptions have been improved. Deprecated Solr. Server and subclasses have been removed, use Solr. Client instead. The deprecated configuration in solrconfig. Users must remove it from solrconfig. Solr. Client. shutdown() has been removed, use Solr.

Client. close() instead. Windows Xp X64 Professional With All Updates May 2012 Issue more. The deprecated zk. Credientials. Provider element in solrcloud section of solr. Use the correct spelling (zk.

Credentials. Provider) instead. Added support for executing Parallel SQL queries across Solr. Cloud collections. Includes Stream. Expression support and a new JDBC Driver for the SQL Interface. New features and capabilities added to the streaming API.

Added support for SELECT DISTINCT queries to the SQL interface. New Graph. Query to enable graph traversal as a query operator. New support for Cross Data Center Replication consisting of active/passive replication for separate Solr. Clouds hosted in separate data centers.

Filter support added to Real- time get. Column alias support added to the Parallel SQL Interface. New command added to switch between non/secure mode in zookeeper. Now possible to use IP fragments in replica placement rules.

February 2. 01. 6 - Apache Lucene 5. Apache Solr 5. 5. Available. If you are on 5. BINARY. SORTED. Expect it to be default in the next release. API Features. Templates must be UTF- 8 encoded.

Simple. Post. Tool (also bin/post) - filetypes . This is a simple way to require a username and password for anyone accessing Solr’s admin screen or APIs. In built Authorization. Plugin that provides fine grained control over implementing ACLs for various resources with permisssion rules which are stored in Zoo. Keeper. The JSON Facet API can now change the domain for facet commands, essentially doing a block join and moving from parents to children, or children to parents before calculating the facet data. Major improvements in performance of the new Facet Module / JSON Facet API. Query and Range Facets under Pivot Facets.

Just like the JSON Facet API, pivot facets can how nest other facet types such as range and query facets. More Like This Query Parser options. The More. Like. This QParser now supports all options provided by the MLT Handler.

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. Added Schema API support in Solr. JAdded Scoring mode for query- time join and block join. Added Smile response format. See the Lucene CHANGES. Solr CHANGES. txt files included.

June 2. 01. 5 - Apache Lucene 5. Apache Solr 5. 2. Available. It's now fast. Requests are not distributed evenly if the collection isn't present locally.

See the Lucene CHANGES. Solr CHANGES. txt files included. June 2. 01. 5 - Apache Lucene 5. Apache Solr 5. 2. Available. Includes optimized Intersect predicate to avoid many geometry checks. Uses Two. Phase. Iterator. New Limit. Token.

Offset. Filter that limits tokens to those before a configured maximum start offset. New spatial Packed. Quad. Prefix. Tree, a generally more efficient choice than Quad. Prefix. Tree, especially for high precision shapes. When used, you should typically disable RPT's prune. Leafy. Branches option. Expressions now support bindings keys that look like zero arg functions.

Add Span. Within. Query and Span. Containing. Query that return spans inside of / containing another spans. New Spatial . It is a set of shapes implemented using 3. D planar geometry for calculating spatial relations on the surface of a sphere. Shapes include Point, BBox, Circle, Path (buffered line string), and Polygon.

Various bugfixes and optimizations since the 5. Highlights of this Solr release include. Blog post: https: //lucidworks. Distinct' and 'distinct.

Values'. It isn't the default, but a parallel UI interface in this release. Solr has internally been upgraded to use Jetty 9. Both releases contain a number of new features, bug fixes, and optimizations. See the Lucene CHANGES. Solr CHANGES. txt files included. April 2. 01. 5 - Apache Lucene 5. Apache Solr 5. 1.

Available. This can mean, on upgrading to 5. Reduced heap usage. Lucene now supports random- writable and advance- able sparse bitsets (Roaring. Doc. Id. Set and Sparse. Fixed. Bit. Set), so the heap required is in proportion to how many bits are set, not how many total documents exist in the index. Heap usage during Index. Writer merging is also much lower with the new Lucene.

Codec, since doc values and norms for the segments being merged are no longer fully loaded into heap for all fields; now they are loaded for the one field currently being merged, and then dropped. The default norms format now uses sparse encoding when appropriate, so indices that enable norms for many sparse fields will see a large reduction in required heap at search time.
