The Search field provides a text field at the top of the screen. When you enter some text and tap the Search button on the keyboard, Strip searches for all names and values that match what you’ve entered with a sub-string query (e.g. ‘.query.’).
For example, if you have an Entry titled “Wall Safe” with a numeric PIN field and another Entry titled “Bank Account” that has a note with the text “Safety deposit info…”, searching for the text ‘safe’ will return both entries.
