To use Advanced Filters on a project, go to your Projects tab and click More Filters, just next to Project Search.
Once you've clicked More Filters, it will bring up Advanced Filters. Below is what it should look like after you've taken the appropriate steps.
Using Advanced Filters, you can select the Location, within a certain mile radius and the zip code of the project. In addition, you can search by State. It also gives you the ability to filter it by Construction Type, Project Types, Project Building Use, Trades, Sector & Labor Status, Live Projects, Old Projects, and the Bid Due Date.
