Find all polygons containing the point

[yashhema]

Hello,
I indexed MultiPolygon using this
IDictionary<string, string> margs = new Dictionary<string, string>
{
["SpatialContextFactory"] = typeof(NtsSpatialContextFactory).FullName
};

        var ctx = SpatialContextFactory.MakeSpatialContext(margs, GetType().Assembly);
          SpatialPrefixTree trie = new QuadPrefixTree(ctx, 12);
        _locationfindstrategy = new TermQueryPrefixTreeStrategy(trie, "geo");

then indexed each polygon via
IShape area = ctx.ReadShapeFromWkt(v.wktstr);
Document doc = new Document();
doc.Add(new TextField("id", v.stname, Field.Store.YES));
Field[] fields = _locationfindstrategy.CreateIndexableFields(area, 0.025);
foreach (Field field in fields)
{
doc.Add(field);
}

Now I am trying to search documents containing a point (For example , say i want to find the city from lat/long, and I have stored polygon shapes of city )

IPoint upperleft = ctx.MakePoint(92.515830993652514, 10.8976411819458);
Query query = _locationfindstrategy.MakeQuery(new SpatialArgs(SpatialOperation.Contains, upperleft));

        TopDocs search = searcher.Search(query, 10);

I am getting error - Opeation Not supported

Is there any other mechanism which i can use
