Apache Lucene.Net is a port of the Lucene search engine library, written in C# and targeted at .NET runtime users.
== Summary == While the project had stalled in the first half of 2019, there has been some progress in the last quarter: * A new YAML CI configuration was setup on Azure DevOps, which was designed so anyone can build and test on their own Azure DevOps account * The test framework APIs were cleaned up and several bugs addressed * Progress is being made on ICU4N, our biggest dependent project * The API doc website is coming along We also added Shannon Deminick as a new committer on October 9, 2019, which is our first since September 2016. There has been very little activity on the user and dev lists in the past couple of months, and there hasn't been any new bug reports in some time. We have itemized the remaining issues for both Lucene.NET and ICU4N and have arrived at the following estimates to production release: Lucene.NET 4.8.0 Hours Completed: ~3700 Hours Remaining: ~750 ICU4N 60.x Hours Completed: ~350 Hours Remaining: ~450 (assuming we don't port any more of it) Hours Remaining: ~900 (ported to feature completion) Lucene.NET 8.x Upgrade Hours Completed: 0 Hours Remaining: ~1700 The primary items left to complete for the 4.8.0 release are the RandomizedTesting package that the test framework depends on, the API docs, and ICU4N. == Releases == * Last Release 3.0.3 - Oct 2012 * Working toward 4.8.0 - Currently beta0006, released 2019-08-13 == People == * Last PMC Member added May 2017, Shad Storhaug (nightowl888) * Last committer added Oct 2019, Shannon Deminick (shazwazza) * PMC Chair rotated 20 June 2018 to Shad Storhaug (nightowl888) == Statistics == As of 2019.10.10 Metric are as follows (followed by metric from 2019.08.19 for comparison): Release 3.0.3 * Lucene.Net 3.0.3: 2,737,979 (up from 2,507,308) * Lucene.Net.Contrib 3.0.3: 601,751 (up from 554,455) * Lucene.Net Contrib Spatial: 34,273 (up from 32,467) * Lucene.Net Contrib Spatial.NTS: 6,986 (up from 6,829) Beta 4.8.0-beta00005 (Published 10/24/2017) * Lucene.Net: 177,945 (up from 155,313) * Lucene.Net.Analysis.Common: 164,168 (up from 142,723) * Lucene.Net.Analysis.Kuromoji: 5,070 (up from 4,484) * Lucene.Net.Analysis.Phonetic: 2,506 (up from 1,962) * Lucene.Net.Analysis.SmartCn: 583 (up from 541) * Lucene.Net.Analysis.Stempel: 1,141 (up from 1,090) * Lucene.Net.Benchmark: 523 (up from 507) * Lucene.Net.Classification: 1,065 (up from 1,030) * Lucene.Net.Codecs: 3,125 (up from 2,835) * Lucene.Net.Expressions: 6,065 (up from 5,577) * Lucene.Net.Facet: 8,794 (up from 7,369) * Lucene.Net.Grouping: 10,059 (up from 8,311) * Lucene.Net.Highlighter: 5,251 (up from 4,695) * Lucene.Net.ICU: 923 (up from 868) * Lucene.Net.Join: 9,055 (up from 7,624) * Lucene.Net.Memory: 9,171 (up from 8,121) * Lucene.Net.Misc: 6,507 (up from 6,035) * Lucene.Net.Queries: 144,937 (up from 125,839) * Lucene.Net.QueryParser: 138,434 (up from 119,881) * Lucene.Net.Replicator: 560 (up from 549) * Lucene.Net.Sandbox: 144,268 (up from 125,906) * Lucene.Net.Spatial: 5,553 (up from 4,615) * Lucene.Net.Suggest: 5,604 (up from 5,185) Beta 4.8.0-beta00006 (Published 08/13/2019) * Lucene.Net: 4,989 (up from 133) * Lucene.Net.Analysis.Common: 4,351 (up from 98) * Lucene.Net.Analysis.Kuromoji: 93 (up from 50) * Lucene.Net.Analysis.Phonetic: 72 (up from 42) * Lucene.Net.Analysis.SmartCn: 138 (up from 42) * Lucene.Net.Analysis.Stempel: 62 (up from 44) * Lucene.Net.Benchmark: 47 (up from 36) * Lucene.Net.Classification: 91 (up from 41) * Lucene.Net.Codecs: 93 (up from 43) * Lucene.Net.Expressions: 65 (up from 41) * Lucene.Net.Facet: 125 (up from 44) * Lucene.Net.Grouping: 141 (up from 45) * Lucene.Net.Highlighter: 240 (up from 51) * Lucene.Net.ICU: 125 (up from 41) * Lucene.Net.Join: 140 (up from 46) * Lucene.Net.Memory: 259 (up from 57) * Lucene.Net.Misc: 139 (up from 49) * Lucene.Net.Queries: 4,024 (up from 90) * Lucene.Net.QueryParser: 3,989 (up from 90) * Lucene.Net.Replicator: 53 (up from 40) * Lucene.Net.Sandbox: 3,992 (up from 118) * Lucene.Net.Spatial: 98 (up from 42) * Lucene.Net.Suggest: 130 (up from 44) * lucene-cli: 74 (up from 49)
