> As of May 1st, 2019, Japanese era '元号' (Gengo) will be set to '令和' (Reiwa). See
this article for more details:
> [https://www.bbc.com/news/world-asia-47769566]
> Currently '令和' is splitted up to '令' and '和' by {{JapaneseTokenizer}}. It should
be tokenized as one word so that Japanese texts including era names are searched as users
expect. Because the default Kuromoji dictionary (mecab-ipadic) has not been maintained since
2007, a one-line patch to the source CSV file is needed for this era change.
> Era name is used in many official or formal documents in Japan, so it would be desirable
the search systems properly handle this without adding a user dictionary or using phrase query.
:)
> FYI, JDK DateTime API will support the new era (in the next updates.)
