Added JSON bools and numbers to direct field look-up.
Removed !new_filter.redo contingency and increased doc count.
Changed automatic filters to use fixed value syntax.
Changed autocomplete to load suggestion sequentially.

For 5000+ rows such a request might take 5000ms to complete and this made me
wonder what the autocomplete suggestions are waiting for.
AMEND-REBASE US SOMEWHERE!! WE ARE EMBARRASING!!!
WIP: Allow multiple direct keys with /^(<KEY>|...)$/.
