How do I refine my search and build a multi-term search query in the CFR?
When searching for a title number or name, part number or name, or even a section, you could get several hits in your search results because a title or part appears several times in multiple volumes across multiple years. Therefore, it is best to refine your search as best as you can, to target the results.
In the below examples, we will search for the section 160.204 in Title 33, Part 160 that displays the inclusion of Ammonium Nitrate in the Definitions. We know the final rule was in place during 2005, thus we’ll narrow our search to 2005.
Begin by using the Advanced Search option at the top of the main page.
You can also search using the Full Text tab at the top of the main page. From here you would type part:160 AND text:”ammonium nitrate” AND text:160.204 AND title:33 and hit the search button.
Once you have your results, you can narrow down tot he year 2005 using the date facets on the left side.
