In my understanding from reading the oniline documentation, LatLonPoint is used for BKD indexing, and LatLonDocValuesField is used for Sort argument's input.
But does it means if a POI has a GeoPoint type "location" field, then i must add the same location value to the 2 fields which makes me confusing: because the api exposes internals to api users... There seems 2 kind of Fields: one is the normal XxxField which is for indexing and is row-stored, the other (XxxDocValuesField) is column-stored, LatLonPoint may be taken as indexing field... In my opinion, the 2 fields are both stored, so StoredField's naming is somewhat misleading, if i add another StoredField with the same field name, then later when using List<IndexableField> L = doc.getFields(); to retrieve the document fields, i only get the last StoredField value, LatLonDocValuesField is not got.
