Hi, you can use the lucene-expressions module and use the distance function there as part of the score. In general, just sorting by distance brings bad user experience, because you would ignore the score completely. So you should just "tune" the score by taking the distance into account, e.g. newscore = score / distance. And you can do this with expressions, the formula can be given as Javascript function, see https://lucene.apache.org/core/5_3_0/expressions/index.html (haversin function is giving distance on earth).
If you want to hardcode the stuff in plain java, you can also use CustomScoreQuery from the lucene-queries module: https://lucene.apache.org/core/5_3_0/queries/org/apache/lucene/queries/CustomScoreQuery.html You can use this query and change the score of the inner query ("subquery") and provide a CustomScoreProvider or FunctionQuery. For both solutions you need latitude and longitude as a DocValues field.
