+ The simplest example of a Prefix Query would be something like
+ <screen>
+ f knuth
+ </screen>
+ or
+ <screen>
+ f "donald knuth"
+ </screen>
+ In those queries no attributes was specified.
+ This leaves it up to the server what fields to search but
+ most servers will search in all fields. Some servers does not
+ support this feature though, and require that some attributes
+ are defined. To add one attribute you could do:
+ <screen>
+ f @attr 1=4 computer
+ </screen>
+ where we search in the title field, since the use(1) is title(4).
+ If we want to search in the author field <emphasis>and</emphasis>
+ in the title field, and in the title field using right truncation
+ it could look something like this:
+ <screen>
+ f @and @attr 1=1003 knuth @attr 1=4 @attr 5=1 computer
+ </screen>
+ Finally using a mix of Bib-1 and GILS attributes could look
+ something like this:
+ <screen>
+ f @attrset Bib-1 @and @attr GILS 1=2008 Washington @attr 1=21 weather
+ </screen>
+ </para>
