Advanced Search may be used to build a query to deliver refined search results. The advanced search window allows users to specify search criteria which builds a query expressed in a URL, displayed at the bottom of the advanced search window. For example, in Advanced Search, a query for term "water" and category of "Data" generates the following URL query: https://www.sciencebase.gov/catalog/items?q=water&filter=browseCategory%3DData. Users may also build the URL queries manually.
Hint: to exclude specific elements, use ! (exclamation point). For example, to find the term water, but eliminate records in the "Data" category, the URL query is: https://www.sciencebase.gov/catalog/items?q=water&filter=browseCategory!%3DData. The ! is inserted after BrowseCategory to eliminate the Data Category from search results.
