in general: you wouldn't you would have to specify all options as init params for the FieldType -- which makes it pretty horrible for distance calculations, and isn't something i considered when i posted that. the only way i can think of that you can really solve the problem with a plugin at the moment (without some serious internal changes that yonik describes below) would be to use a dynamicField when you want geodistance sort, and encode the center lat/lon point in the field name, ala: sort=geodist_-124.75_93.45 : or extend solr's sorting mechanisms to allow specifying a function to sort by. : : sort="dist(10.4,20.2,geoloc) asc" thta would in fact, kick ass. even if there is a better solution for the distance stuff the idea of being able to specify a raw function as a sort would be pretty sick. (NOTE: that's "sick" as in "so good it's amazing" ... since the last person i used that idiom with didn't understand and thought i ment "bad") -Hoss
