Geo function in aggregate query throws exception

[dai-chen]

Because geo function support is missing in new engine, the following falls back to old engine which cannot handle. May need to add support for common geo functions.

SELECT sum(id) AS id FROM index WHERE GEO_INTERSECTS(geo, '\''POLYGON ((102 2, 103 2, 103 3, 102 3, 102 2))'\'')
{
  "error": {
    "reason": "Invalid SQL query",
    "details": "unsupported method: geo_intersects",
    "type": "SqlParseException"
  },
  "status": 400
}
