// Include immediately after elasticlunr.min.js in the JS bundle.

// elasticlunr's UMD assigns window.elasticlunr. Keep a local binding for search.js
// in this same bundle, and expose window.lunr only long enough for optional
// on-demand language packs (lunr.stemmer.support.min.js, lunr.fr.min.js, …).
// Those scripts mutate the same object; after they run we drop the global name.

// run in document order before DOMContentLoaded, so stemmer/lang packs attach
// first; then we remove the temporary global. Local `elasticlunr` still has
// stemmerSupport / language plugins for search.
