: Problem : For those documents which doesn't have latlng field, value is
coming exceptionally large '8763.191'.
I'm pretty sure you're seeing the function assume a default lat,lon of
"0,0" for docs thta you haven't given a position.
If you don't have a location on every doc, you're probably going to want
to use a filter query to exclude docs that have no location -- i'm not
sure off the top of my head how to do that.
: How can I limit this maximum distance(i.e score) as 25?
apply another fq that filters by distance, either using bbox or geofilt...

...but you'll still want to find a way ot filter out docs with no latlon
values, otherwise you're going to get false positives if your input point
ever happens to be within 25km of "0,0"
