There is no ActiveRecord API for materialized views, so we need to write raw SQL to make our search index
Includes a materialized view using postgres’s native ts_vectors
This is only necessary until we can upgrade to CircleCI 2.0
While it might seem right not to stem people’s names when building the index, since we’re going to stem the search queries indiscriminately, that’s the only way it will match

This PR adds search to the library. The full text of the cases can be searched, for which the title, dek, kicker, and summary are weighted highest; the titles of pages, podcasts, and activities, and the authors names are weighted second highest; and the contents of paragraphs are weighted third highest. Search is implemented in Postgres with an indexed materialized view of ts_vectors, so it’s really fast.
The search results view is also overloaded as the sub-indexes: while
/catalog/search?libraries[]=michiganand/catalog/libraries/michiganshow the same cases, the latter also displays a blurb about the MSC Library and functions as its directory page.Migrations: HELL YES
