Low Search prefetch number of entries

Question

I'm trying to pre-fetch the number of results available per year for a specific category of articles.

The loopee module allows me to loop from current year back to 1999. I would like to show a filter available (possibly with the number of entries available) only if there are results for that specific year and that specific category.

Example:

Sports

2016(5) | 2015(4) …

{exp:channel:categories channel="articles" style="linear"}
    <h1>{category_name}</h1>
    {exp:loopee forint="{current_time format="%Y"}" to="1999" by="-1" parse="inward}
        {exp:low_search:filters query="{segment_3}"}
(IF) ONLY SHOW FOLLOWING CODE IF THERE ARE ENTRIES AVAILABLE                
            <span>
                <a href="{low_search:url collection="articles" category="{category_id}" search:anno="{loopee_value}"}">{loopee_value}(X) | </a>
            </span>
(/END IF)
       {/exp:low_search:filters}
    {/exp:loopee}   
{/exp:channel:categories}

This is not something Low Search can do for you. You generate the form (or links) that contain the parameters to filters. LS uses a combination of native and its own filters, and EE lacks the API to get to just a results count based on those params (ie. Generating context-aware totals per parameter value)
