Managing search strategies using document-centric tools such as MS Word or PDF introduces errors through unwanted conversion of control characters (e.g. Search strategies can be improved thorough peer-review, but the platforms used for this practice are not always open to public scrutiny Systematic literature review is the cornerstone of evidence-based medicine, but published search strategies often contain errors Moreover, this approach precipitates a number of other issues: However, these tools require the use of complex Boolean syntax and offer limited support for error checking or optimization. But there are times when a more rigorous, precise approach is needed.įor example, researchers, information professionals, patent searchers and recruiters all require effective search to perform their duties, often relying on advanced search tools such as form-based query builders. Sometimes, a few keywords in a search box are good enough. For example, 01.2047-100 is considered 2 numbers: 01.2047 and 100.Finding the right information at the right time is a constant challenge. Note: When using numbers as part of your query, a space or a dash (-) will separate a number while a dot (.) will be a decimal. Note: Labels are only added to a message, and not an entire conversation. Messages with a certain message-id headerĮxample: that have or don't have a label Messages larger or smaller than a certain size in bytes Messages larger than a certain size in bytes Search for messages older or newer than a time period using d (day), m (month), and y (year) Search for messages sent during a certain time period Note: You can't find messages that you received on bcc. Messages that include an icon of a certain color Starred, snoozed, unread, or read messages
Search for messages that are marked as important Messages in any folder, including Spam and Trash Messages that have a Google Drive, Docs, Sheets, or Slides attachment or linkĮxample: with a certain name or file type
