public interface IMapServerFindResult
Provides access to the Map Server Find Result Interface.
MapServerFindResult honors field visibility and field aliases set in the source map.
MapServerFindResult includes a number of properties. Value and FieldName return respectively the value and field’s name of the primary display field for the feature. FeatureProperties returns a set Field-value pairs. These are returned as strings. This also includes the Shape field. To get geometry do not use the Shape field contained within the FeatureProperties’ field-value pairs, use the FeatureShape property instead. If you are interested in information about the layer that the feature belongs to you can use LayerID.
In order to control the amount of information MapServer needs to process for a query, a maximum number of records can be set. This value is contained in the MaxRecordCount property on IMapServerInit2. The default value for this property is 500. If 600 features match a given query only the first 500 results will be returned. You will be unable to access the remaining 100 records. To be able to access these records the MaxRecordCount would need to be increased to 600.
Use IMapServerFindResult to access properties of map features returned as a result of using the IMapServer Find method.

FeatureShape contains the geometry of a feature returned from a MapServer Find query. This geometry have the same spatial reference system as the DefaultMapDescription. When ILayerResultOptions is not used, the FeatureShape property returns geometry. If the Shape field is invisible in the source map, the FeatureShape property may still contain geometry depending on how IncludeGeometry is set by the user.
In some cases, for performance reasons, you may want limit or adjust the geometry being returned. Use ILayerResultOptions to manage this. If IncludeGeometry is set to False, FeatureShape returns nothing. This should increase performance in cases where feature geometry is large. You can also choose to densify or generalize the geometry returned in FeatureShape using GeometryResultOptions. Densification is used to better support clients that do not support Arcs (e.g. Bezier, Circular etc.). Generalization reduces the amount of geography being sent across the network and should lead to better performance.
Densified or generalized geometry should only be used for navigation or display purpose, such as zooming to, flashing, or highlighting the selected feature. For spatial queries, GeometryResultOptions should not be used as it may returns unexpected results. For more information on please see IGeometry, Densify, and Generalize .
