In-Depth Information
The most commonly used section of the
Search
interface (
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).
Searching criteria by column—query by
example
The main use of the
Search
panel is to enter criteria for some columns 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
inding the topic with ISBN
1-234567-89-0
. We simply enter this value in the
isbn
box
and set the
Operator
field to
=
.
