Allow user to search within bookmarks

User story

As a user with many bookmarks, I would like to search within my bookmarks.

Concrete example

A simple Ctrl-F/Command-F browser search won't be sufficient in either of two scenarios:

• If a user has enough bookmarks for pagination to kick in (they may miss bookmarks that are on other pages)
• If a user wishes to search using a field that is not displayed in the index view present on the bookmarks page (e.g. some metadata that is only displayed on the show page, or is only indexed for searching)

This is a really cool idea. One possible implementation could involve passing a list of bookmarked Solr ids to the solr query in order to limit/filter the search to just those specific record ids. Though I think there may be a cap to how many ids can be passed to Solr.
