David Smiley commented on SOLR-14802:
-------------------------------------
the spatial-search.adoc page already documents geodist and refers to these
parameters it takes.
{noformat}
`geodist` is a distance function that takes three optional parameters:
`(sfield,latitude,longitude)`. You can use the `geodist` function to sort
results by distance or score return results.
{noformat}
The issue here addresses a shortcoming so that it actually works with basically
most spatial fields today. That one line mentioning these parameters had
become somewhat obsolete for a number of years, and is now more accurate again
:-). I suspect the latitude & longitude aspect part may be outdated; you're
expected to use the "pt" param like all the examples show.

> Previously using geo field with type LatLonType you could implement a query
> like
> {code:java}
> /select?q=*:*&fl=ID&fq={!geofilt}&d=50&pt=53.4721936,-2.24703&sfield=MAIN_LOCATION&sort=min(geodist(),
> geodist(ALT_LOCATION,53.4721936,-2.24703)) asc{code}
> to sort results on minium distance from multiple different locations. Moving
> the fields to advised LatLonPointSpatialField gives
> "geodist() does not support field names in its arguments when stated fields
> are solr.LatLonPointSpatialField spatial type, requires sfield param instead"
> This has been reviewed before SOLR-11601 but not for my actual actual
> use-case so it seems the choice was to just change the error message rather
> than to implement the previous functionality. Can this be re-reviewed or let
> me know if there is another way to achieve the same result.
