Think of all of the potential kinds of facets:

* `?_facet_array=tags` where tags is a JSON array of values
* `_facet_date=datetimecol` - faceted by date part of a datetime
* `_facet_bins=numeric_column` - can I do some kind of fancy binning here? Might need to take an argument
* `?_facet_bins=numeric_column:5` - could be a way to take an argument. We’ll ignore columns with a : in their name.
* `?_facet_json=jsoncol:jsonpath` - could use a JSON path to extract out something to facet on?
* `?_facet_percentile=numericcolumn` - could this work?
* `?_facet_function=column:sqlfunctionname` - maybe this could be interesting? Would allow for e.g. facet by soundex
* `?_facet_prefix=column:prefix` - facet by terms but only if they start with a specific prefix
* `?_facet_substring=column:3,6` - facet by a substr(column, 3, 6)

Maybe bundling JSON in querystrings is a way to do options?

`?_facet_distance={""latitude_column"":""x"",...}`

Could detect values starting with `{` - and if for some weird reason you have a column starting with that character you can pass this instead: `?_facet_percentile={""column"": ""{value}""}`

This could even be the mechanism that allows us to extend regular facets to support additional options like adding a sum or max to each one.

Problem: it’s not obvious what the name associated with these facets should be. What if one column is faceted multiple times using multiple facet variants?

Maybe just number them? name1=… name2=… etc?

Other option is to use Solr style querystring syntax for notation. Solr does this: `?f.price.facet.range.gap=100&f.age.facet.range.gap=10`

So how about this:

`?_facet_range=age&_facet_range.span=5`

I'd like to also be able to facet by month or year.

I'm not sure what the best way to achieve this is.
