Great work.

For some reason, when I gave it a very broad query I got the suggested result "[Table B18104?] Sex by Age by Cognitive Difficulty (Civilian noninstitutionalized population 5 years and over): Total".

No idea why it picked that table. Instead of the more general "[Table B01003]: Total Population" or "[Table B01001] Sex by Age". In general I think a query's first result hit should be the least specific match.

And the embeddings/full-text-search mishandle things that have no close match: the query "People who look like Kevin Bacon" returns "Number of People: Population by Ancestry: Basque (2022)"
