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