Crate designation_index 

The designation search index.

An fst map over designation word tokens plus roaring posting bitmaps per word, with language, designation-use, language-reference-set, and status filters as bitmaps, sorted by term length then designation ordinal. This is the $expand filter and $find-matches engine for every loaded code system. No spec governs the index format: our own design (docs/architecture.md §Text search).
