Different content types are shown on the left side of the "Advanced Search" Page. Click on a content type to bring up the detailed search page in the right pane ②. "Advanced Search" for laws and regulations provides more search filters (promulgator, document number etc) than the "Quick Search".

If the advanced search brings up no results, you will be asked if you would like to conduct a quick search for the same terms and retrieve those results. Or you can click "Quick Search" (shown below) to submit a quick search for the same terms.
