![]() ![]() John Doe,” or “Reverend John Dae,” or “Rev. Will return either Rev or Reverend and John or Jan within two words of D ?eĮ.g., “Rev. (Optional, Boolean) If true, enable position increments in queries constructed from a querystring search. (Rev OR Reverend ) AND (John OR Jan ) w2 D ? (Note that the search term is placed within parenthesis, and then within another set of parenthesis along with the command.) Will return files only with NJ in the title. In addition, some newspapers printed the date of publication on every page while others did not.)ĬOMPLEX BOOLEAN STRINGS - You can also create strings of Boolean terms, creating ever more specific search parameters. (Note that on Old Fulton, it may look for the dates of the scans, not titles. Inserting a tilde will define a range of dates to search. In this example, inserting two question-marks will allow it to replace two characters, “John,” “Jahn,” etc. The insertion of a question-mark, specifies how many characters can be replaced with wild-cards. (Insert multiple question-marks, to allow for more variables.) In this example it will return “Rev” or Reverend” and “Jonathan,” “John,” or “Jan.” The insertion of an asterisk allows any number of characters to be replaced as wild-cards. Will find documents that have BOTH “John Doe” and “Jane Doe” on the same page Will find a “John” or a “Jane” within two words of “Doe” = “John Doe” or “Jane Doe” NEAR Operator: Inserting n and a number (in this case 10) will find will find results that have “John” and “Doe” near each other, separated by no more than 10 other characters. This can be helpful if a middle name is used, e.g., “Jane Liz Doe,” as it will just look for the two words within two words of each other and ignore what is between them. WITHIN Operator: Inserting w and a number (in this case 2) will find results that have “John” and “Doe” within two words of each other. Results that either have only the whole name “Reverend John Doe” on the page. ![]() Will find documents that have a “John” on the page but no “Doe” on the same page. Boolean operators act on sets - groups of records conta. The Boolean operators, AND, OR, and NOT, help you construct a logical search. Results that have “John” or “Doe” on the same page, note that these terms may not have any relationship to each other. Boolean logic (named after mathematician George Boole) is a system of logic to designed to yield optimal search results. Results that only have John, excluding any result with Jonathan. Results that have “John” and “Doe” on the same page, note that these terms may not have any relationship to each other. Note: Make sure to select “Boolean” from the drop-down menu before hitting “Search.” With Boolean, you can learn a few basic commands and combine them to get ever more specific with what you are looking for. While it may sound daunting, learning a few Boolean terms will help you get more out of sites like Old Fulton, and works with most search engines, such as Google!Ĭontinuing with our example of “Reverend John Doe.” Experiment with adding the following terms to your search and see what happens.
