You can find almost anything you need within your online apps by using their hidden or advanced search features. While many people rely on the familiar search bar, simple searches can yield irrelevant results. Instead, use keyboard shortcuts and special operators to refine your searches in apps like Trello, Slack, Evernote, Facebook, Twitter, Gmail, Google, and LinkedIn. For example, in Trello, you can use `/` to jump to the search box, `@` to find cards assigned to a specific member, and `board:zапиер` to restrict your search to one specific board. In Slack, you can use `/s` to start a new search quickly, and `from:@[team member]` to find all messages from a team member. In Evernote, you can use `notebook:` and `tag:` to search within notebooks or tags, and `resource:` to find notes with attachments. By mastering these advanced search features, you can quickly find the information you need across various apps and streamline your workflow.
