TIPS:
Use quotations around Doctype operators that include ‘and’. Example: Doctype: “acts and statutes”
Type a single term used in multiple Doctype operators to locate combinations of document types. Example: the term "letters" can be found in both Comment Letters and No-Action Letters. By using Doctype: "letters", both document types will be returned.
