Show count of facet values if ?_facet_size=max #1423
Description
I sometimes want to get a count of the values in a facet - if it's a facet of US states for example I want to know if all 50 are represented.
Idea: if ?_facet_size=max is present, add a count to the facet heading. So on:
It could have something like this:
Note that the first column shows >1000 - because in that case we've truncated the facet calculation since the maximum allowed returned rows is 1000.

Problem: on a page which doesn't have quite enough facet values to trigger the display of the "..." link that links to
?_facet_size=maxthe user would still have to manually count the values - up to 30 by default.So maybe the count should always be shown, perhaps as a non-bold light colored number?
I could even hide it in a non-discoverable tooltip.

Could display them always, like this:
That's with
<span style="font-size: 0.8em;color: #666;">23</span>simonw commentedon Aug 6, 2021
Point of confusion: if only 30 options are shown, but there's a
...at the end, what would the number be? It can't be the total number of facets because we haven't counted them all - but if it's just the number of displayed facets that's like to be confusing.So the original idea of showing the counts only if
_facet_size=maxis a good one.simonw commentedon Aug 6, 2021
The invisible tooltip could say "Showing 30 items, more available" (helping save you from counting up to 20 if you know about the secret feature). The numbers could then be fully displayed on the "..." page.

This means that the counts would be unavailable to users who cannot see tooltips (e.g. mobile users) on pages that did not have any facets that broke the 30 limit and hence displayed that "..." link.
I think I'm OK with that, for the moment. May revisit in the future.

I didn't bother with the tooltip, just the visible display if

Great feature.
But what is the right way to enable this to show up? Currently, it seems I need to edit the URL to add, in the right place,
&_facet_size=maxIs there another (easier) way to enable this feature?

You've caused me to rethink this feature - I no longer think there's value in only showing these numbers if
?_facet_size=maxas opposed to all of the time. New issue coming up.Always show count of distinct facet values, closes #1556
