/*
* make-search-index.js
*
* This converts a "search data" file produced by the haskell site builder into
* a lunr.js index and saves it in JSON. Metadata for rendering search output
* (currently titles and tags) are stored separately in an extra file.
*
* Installing dependencies:
* yarnpkg add lunr
*
* Usage:
* site ....some args.... --search-data-output tmp/search-raw.json
* node scripts/make-search-index.js tmp/search-raw.json _site/search-index.json _site/search-metadata.json
