How to search
Choose how to search (e.g. Contains, Starts with...) then enter part of a word or one or more words as preferred.
Suggestions will show, according to what you typed.
You can then either: click a suggestion to show its content. Or, instead, press enter/return on your keyboard to search all content with your entered word(s) or part word, with your search method (Contains... etc).
Then click Search and results of your search will display. Initially, before any search is entered, all items are shown.
