All KeepandShare applications have a powerful search command that will instantly find all items matching your search text. In all of the applications (except calendar) the Search command is an empty field in the Show bar:

To search, simply type one or more words into the search box and click on the Search button. Results are instantly displayed. To clear the search, click on the that appears next to the Search box.

Note that the Search command looks for the entire text sequence you type, even if it is separate words. This is different behavior than internet search engines such as Google, where they look for occurrences of any one of the words you type into their search box. So in KeepandShare, if you type "spring apples", it will not find a document that has only the word "spring" in it, nor a document that has only the word "apples" in it; KeepandShare will only find documents that have the full "spring apples" text in them.

Searches are case-insensitive - that is, capitalization does not matter.

In the Calendar application, click on the green Search button and you can then type your search text in, as well as control the date range the search will occur within.
