Building an Advanced Search Query

Select the Advanced Search link located beneath the main search bar to search particular fields within the metadata (indexing) for more precise results. Search by text, title, creator/author, description, or date. Further refine a search by searching only within certain subcollections. Users may also select a title by citation or define a date range. 

Venn Diagram Search

With the beta release of a Venn Diagram Search, users can visualize the results yield of various keywords to better refine their searches. To use the Venn Diagram feature in the U.S. Presidential Library, select the Advanced Search hyperlink to find the Venn Diagram option within.

Users will be redirected to a search bar, instructions for its use, and example searches. Enter a search for multiple terms separated with the Boolean operators "AND." A Venn diagram will appear, illustrating the various combinations of those terms and their respective results yield throughout the database. The original search combining all terms will appear by default, visually represented by the red intersection of all circles. 

View the results of other combinations by selecting the Clear button above the diagram to be able to hover over the various options. Users will see all possible search term combinations highlighted as the cursor hovers over them. Click one of these highlighted circles or intersections to bring up the results of the various combinations or the results of one term. 

Refining Results

After entering a search query through any of the aforementioned methods, users will be directed to a results page with facets on the left-hand side. These facets allow users to limit their results by Date, Document Type, Section Type, Title, and Person. 

Tip: Begin a search using more general terms and utilize facets for more precise results.
