I'm still thinking about how a plugin / separate tool could work that builds a single FTS index over the content from multiple tables such that you can run relevance-calculated queries against those multiple tables.

Since that's going to be a plugin / separate tool too, I'm closing this issue.","{""total_count"": 0, ""+1"": 0, ""-1"": 0, ""laugh"": 0, ""hooray"": 0, ""confused"": 0, ""heart"": 0, ""rocket"": 0, ""eyes"": 0}",451513541,

http://sf-trees.datasettes.com/trees-b64f0cb?sql=select+name+from+sqlite_master+where+name+like+%22%25_fts%22+and+type+%3D+%22table%22

`select name from sqlite_master where name like ""%_fts"" and type = ""table""`

You could then construct a crafty UNION query to get results back from all of those tables at once:

(I'm searching for `fi*` here to demonstrate wildcards)

The problem, as discussed earlier, is relevance: there's no way to compare the scores you're getting across different tables, so you won't be able to order by anything.

I've had a lot of success building small apps on top of Datasette's JavaScript API - I wrote up one example here: https://24ways.org/2018/fast-autocomplete-search-for-your-website/

Once #272 is done I'll be adding a plugin hook that allows plugins to define entirely new pages within the Datasette application, which may also be a good way to work on this.","{""total_count"": 0, ""+1"": 0, ""-1"": 0, ""laugh"": 0, ""hooray"": 0, ""confused"": 0, ""heart"": 0, ""rocket"": 0, ""eyes"": 0}",451513541,

One challenge here is that FTS ranking calculations take overall table statistics into account, which means it's usually not possible to combine rankings from different tables in a sensible way. But that doesn't mean it's not possible to return grouped results.

I think this makes a lot of sense as a plugin.","{""total_count"": 1, ""+1"": 1, ""-1"": 0, ""laugh"": 0, ""hooray"": 0, ""confused"": 0, ""heart"": 0, ""rocket"": 0, ""eyes"": 0}",451513541,
