selectFeatures不能查找到数据

代码如下：

map.on("click", function(evt) {        selectQuery.geometry = evt.mapPoint;        selectQuery.distance = 50;        selectQuery.units = "kilometers"        selectQuery.returnGeometry = true;        // selectQuery.spatialRelationship = Query.SPATIAL_REL_CONTAINS;        teamsFL.selectFeatures(selectQuery, FeatureLayer.SELECTION_NEW, function(features) {          if (features.length > 0) {            //store the current feature            updateFeature = features[0];            map.infoWindow.setTitle(features[0].getLayer().name);            map.infoWindow.show(evt.screenPoint, map.getInfoWindowAnchor(evt.screenPoint));          }          else {            map.infoWindow.hide();          }        });      });

查询结果数量一直为0，不论把distance的值变为多大。

原因，发布的数据不支持Query的distance查询方式，高级的缓冲区查询方式。

An object that contains service level metadata about whether or not the layer supports queries using statistics, order by fields, DISTINCT, pagination, query with distance, and returning queries with extents. This object contains the existing properties supportsStatistics andsupportsAdvancedQueries which is returned in the new supportsOrderBy property. For backward compatibility supportsStatistics andsupportsAdvancedQueries will remain properties of FeatureLayer.

<span style="font-size:18px;">"advancedQueryCapabilities" : {  "supportsPagination" : true,   "supportsQueryWithDistance" : true,   "supportsReturningQueryExtent" : true,   "supportsStatistics" : true,   "supportsOrderBy" : true,   "supportsDistinct" : true}</span>

supportsAdvancedQueries

When true, the layer supports orderByFields in a query operation. Requires ArcGIS Server service version 10.1 or greater (Added at v2.6)

supportsAdvancedQueries是发布图层的属性，发布的数据要在arcgis10.1版本以上，才支持这种查询方式。
