Once you are satisfied with your search query, you can press the search button. The search service will return a list of SPRs matching your query, which in turn you can visit by clicking on them.
If a field in the search form is omitted, the search service will assume
that you are looking for any match for that particular field. In fact,
if you just press the search button right away, the search service
will return all SPRs
An SPR consists of fields that contain information.
The search service allows you to specify one or more fields and a regular
expression that you want to test them against.
The text area on the form lets the user to specify an advanced query,
allowing to search for almost anything.
A field pattern match consists of:
Field Binder /Pattern/[i]The patterns can be combined with the operators and,&&, or,||, and not,!. The patterns can also be grouped by brackets ().The binder operators =~ and its counterpart !~ bind the field to a pattern match. The optional i specifies to ignore case (matches upper or lower case).Field RelationalOP Value
Example: %Title% =~ /rsim/i
Field EqualityOP ValueThe relational operators gt,ge,lt,le and equality operators eq,ne compare strings.
Example: %Date% ge "1999-04-01"
A more complex example combines the above:
%Date% ge '1999-03-01' and
%Date% le '1999-04-01' and
not %Originator% =~ /erd/i
One final note. The advanced search mechanism does not check the
validity of the complete expression. As a result the service will not respond.
In that case, go back to the search form, and revisit your query on typos.
