Need help on defining custom scorer in Lucene 9
Hi Team,

I am little bit familiar with Lucene, and I have a problem statement in
hand to score each document based on the value of the field.

Value will be of type
GeoPoint {
Lat
Long
}

And in the qry I will be getting other pair of lat, long and distance from
that lat long.
I have figured out on calculating distance of lat long on the basis of
input params
But I am having hard time in implementing such custom scoring function.
Any help / pointers/ examples / sample code snippets will be
of great help.

Looking forward to hearing from you.

Thank you so much in advance!

Regards,
Lokesh

Hi Lokesh

IIUC each document (like for example a shop description) has a longitude
and a latitude associated with.

The user search input are some keywords and the the user's geo location.

The keywords you use to search for the documents and the users's geo
location you would like to use for sorting the search results set,
whereas the sorting would depend which locations are the nearest to the
user's geo location.

Is this your use case?

Thanks

Michael
