Explore Content allows you to browse all the documents in Secrets Files from World Wars to Cold War. You can use the filter options such as date, theme, document type, country, and language to restrict the number of documents being displayed.
Synonym search allows a given search term to automatically retrieve variants of that term. For example, a search for "USSR" with synonym search enabled will return results for "Soviet Union" and "Russia". To run a synonym search, select Use Synonyms on the Quick Search page or the Advanced Search page. To search for a specific term only, deselect Use Synonyms on the Quick Search and Advanced Search pages.
Phrase searching is supported on this platform. To complete a phrase search, encapsulate the term in quotation marks, for example by typing "Soviet Union".
Stem searching is the comparison of a search term to the root form of the word(s) used in that search term. For example, a user may search for the term "calmer", but turning on stem searching will also return search results for any word that contains the root form of the term (e.g. "calm", "calmed", "calmer"). Stem searching is switched off by default, but can be turned on by selecting the tick-box titled Use Stemming next to the search bar. To search for a specific term only, ensure that the Use Stemming tick-box is deselected on the Quick Search and Advanced Search pages.
Advanced search overview
Wildcards are supported on the site and can be used in all search fields. They can be used in a search query to represent an unknown character.
- The asterisk (*) represents any group of characters, including no character

Selecting the Return to Advanced Search link from the search results will enable you to return to your previous search query (prepopulated fields and filters) and edit or delete as you wish.
