In-Depth Information
The most commonly used section of the Search interface (the query by example) is
the one immediately displayed, whereas other dialogs are hidden in a slider that can
be activated by the Options link (more on these dialogs later in this chapter).
Search criteria by field—query by example
The main use of the Search panel is to enter criteria for some fields so as to retrieve
only the data we are interested in. This is called query by example because we give
an example of what we are looking for. Our first retrieval will concern finding the
book with ISBN 1-234567-89-0 . We simply enter this value in the isbn box and choose
the Operator ' = '.
Clicking on Go gives these results (shown partially in the following screenshot).
