+ * 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
