BUGFIX: Chinese search was broken
BUGFIX: User locale was used index data
BUGFIX: missing Norwegian fulltext config
FEATURE: store the text used to index stuff in fulltext (for diagnostics / in page search)
FEATURE: re-index posts when locale changes (in bg job)
FEATURE: allow reindexing by trucating post_search_data

Note: I removed japanese specific config cause it requires custom pg config,
  happy to add it once our base docker config ships with it
