[discovery] Discovery Weekly Update for the week starting 2018-10-15

This is the weekly update from the Search Platform team for the week starting 2018-10-15. As always, feedback and questions welcome. == Discussions == === Search === * Trey completed his analysis of the Nori language analyzer for Korean. [0] With appropriate customizations, it should improve search on Korean-language wikis, though we won't be able to use it until we upgrade to Elasticsearch 6.4.2. Thanks to Baha and Revi for their help reviewing the output of the language analyzer. [1] * Mathew and Gehel worked on reconfigure=ing Icinga alert for elasticsearch_shard_size to reduce false positive alerts [2], as well as working on refactoring to 'use_git_deploy' in wdqs puppet module to cater for scap3 and autodeployment modes [3] * Erik worked on repairing some search satisfaction browser tests that were no longer automagically running [4] === WIkidata Query Service === * Query Lexemes are now in production for the Wikidata Query Service that entailed a large amount of work and dedication from Stas [5] * Mathew and Gehel created an auto-deployment test server for WDQS [6] == Did you know? == * The writing system for Korean, called Hangeul or Hangul, [7] consists of 24 characters (14 consonants and 10 vowels), which can be combined into 11,172 modern syllable blocks. Each of the modern syllable blocks has its own Unicode character, while obsolete syllable blocks can be composed of individual characters (if you have a font that is smart enough to know what to do [8]). Hangeul thus combines the features of an alphabet and a syllabary, and has been called a "syllabic alphabet" and an "alphabetic syllabary".
