3. Click the icon. Step-by-step query instructions will appear in the Information Bar.
   
   
4. Follow these instructions carefully to perform both simple and complex queries.
   
   
5. When you are finished with your the query instructions, you will click the Execute button to perform the query on the map. Or you can click the Clear button to start over. After executing a query, the results will be displayed in the Information Bar in an attribute table.

Or click on the "Zoom to these records" hyperlink at the bottom of the table to zoom to the extent of all of the spatial features in the table. If you click on one of the hyperlinked numbers in the "Zoom To" field, the spatial feature will be zoomed in and highlighted in yellow or orange on the Interactive Map. The yellow represents all of the spatial features that match your query, and the orange represents the unique feature that you selected to zoom in on. Look at the picture below:
