full text search (not including lemmatisation yet)

this basically involves porting over our existing search and ES infrastructure but dedicated to just Homer.

note that there's no separate search page, this would entirely be done via a widget but that widget could be in the main pane.

With the Work --> {Divisions|Superheadings|Sections} --> Token hierarchy, can likely simplify how indexing works.

Indexing has traditionally also been doing some of the lemmatization, but we can end up having that in "cold storage" as part of the data plan and indexing really is just indexing.

Should think through how GraphQL might wrap our existing search API (so we can return "results" in a similar format as we serve up books / lines / tokens)
