我正在尝试搜索特定半径内的结果，并根据与点的距离（近先，远后）对结果进行排序。但是，返回的结果排序相反（远先，近后）。
这是我的代码：
string name = "__Location";
var strategy = new PointVectorStrategy(ctx, name);
var indexSearcher = new IndexSearcher(_dir, true);
double radious = Double.Parse(rad);
double lat = 33.8886290;
double lng = 35.4954790;
var distance = DistanceUtils.Dist2Degrees(radious, DistanceUtils.EARTH_MEAN_RADIUS_MI);
var spatialArgs = new SpatialArgs(SpatialOperation.Intersects, ctx.MakeCircle(lng, lat, distance));
var spatialQuery = strategy.MakeQuery(spatialArgs);
Point pt = ctx.MakePoint(lng, lat);
ValueSource valueSource = strategy.MakeDistanceValueSource(pt);
ValueSourceFilter vsf = new ValueSourceFilter(new QueryWrapperFilter(spatialQuery ), valueSource, 0, distance);
var filteredSpatial = new FilteredQuery(new MatchAllDocsQuery(), vsf);
var spatialRankingQuery = new FunctionQuery(valueSource);
BooleanQuery bq = new BooleanQuery();
bq.Add(filteredSpatial,Occur.MUST);
bq.Add(spatialRankingQuery,Occur.MUST);
TopDocs hits = indexSearcher.Search(bq, 10);
我如何从最近到远对结果进行排序？
我正在使用：

谢啦
这似乎是Lucene.Net. Contrib.Sspace al中的一个bug，所以我写了一个可以解决问题的新距离值源类，叫做距离值源，你可以在下面找到类的来源：

这是我现在更新的代码片段：
string name = "__Location";
var strategy = new PointVectorStrategy(ctx, name);
var indexSearcher = new IndexSearcher(_dir, true);
double radious = Double.Parse(rad);
double lat = 33.8886290;
double lng = 35.4954790;
var distance = DistanceUtils.Dist2Degrees(radious, DistanceUtils.EARTH_MEAN_RADIUS_MI);
var spatialArgs = new SpatialArgs(SpatialOperation.Intersects, ctx.MakeCircle(lng, lat, distance));
var spatialQuery = strategy.MakeQuery(spatialArgs);
Point pt = ctx.MakePoint(lng, lat);
DistanceReverseValueSource valueSource = new DistanceReverseValueSource(strategy, pt, distance);
ValueSourceFilter vsf = new ValueSourceFilter(new QueryWrapperFilter(spatialQuery ), valueSource, 0, distance);
var filteredSpatial = new FilteredQuery(new MatchAllDocsQuery(), vsf);
var spatialRankingQuery = new FunctionQuery(valueSource);
BooleanQuery bq = new BooleanQuery();
bq.Add(filteredSpatial,Occur.MUST);
bq.Add(spatialRankingQuery,Occur.MUST);
TopDocs hits = indexSearcher.Search(bq, 10);
现在，结果从最接近最接近的排序！
