SFgate-based forms are HTML
documents that enable to use structured fields features of freeWAIS-sf
via WWW interface.
There are different kinds of SFgate-based forms: the appearance
of three of them is reported below. Their specific features will
be described in next chapters.
Most of these forms are LIVE: if you select their Start
Search button, then you have back record(s) matching your
query.
A. Forms with tags based on freeWAIS-sf fields
This is the simplest kind of form.
In this case you find some Input Boxes referred with labels
that could be the name of the fields they have in freeWAIS-sf
.fmt file or with more descriptive terms.
If there are two or more Input Boxes, then they are connected in
explicit or in hidden way with boolean operators AND or OR.
In the example below, the boolean operators are explicit and
you can choose which one to use.
B. Forms with field selection at the running time
In this case each Input Box
has one or more input tags so that the user can choose at the
running time on which field (s)he wants to search for.
In the example below there are two tags. Each of them has a field
selection with three possible choices:
Please note that this way you can also search twice on the same field. In this specific case (phonebook) you have to connect Input Boxes with the Boolean Operator OR, of course!
C. Forms based on "checkbox" tags
This is another example of SFgate-based form. This kind of form can be used in all the cases in which the content of the searchable fields has a limited number of possibilities. In this kind of forms, if one selects more than a choice, an implicit boolean operator OR connects selected values inside that field.
