"Congress.gov’s release 3.4 was deployed on Monday, June 26th. With this new release, you may have noticed a change in your search results. This is because the default search operator on the global and advanced search form is now AND instead of OR. For example, if you searched national park from the homepage, Congress.gov used to return results for national OR park. With the new release, Congress.gov will return results for the search national AND park. The intent behind this change is to return results that contain both of your search terms, providing you with selections that are more relevant to your search.
