2 The simplest example of a Prefix Query would be something like
3 </p><pre class="screen">
7 </p><pre class="screen">
10 In those queries no attributes was specified.
11 This leaves it up to the server what fields to search but
12 most servers will search in all fields. Some servers does not
13 support this feature though, and require that some attributes
14 are defined. To add one attribute you could do:
15 </p><pre class="screen">
18 where we search in the title field, since the use(1) is title(4).
19 If we want to search in the author field <span class="emphasis"><em>and</em></span>
20 in the title field, and in the title field using right truncation
21 it could look something like this:
22 </p><pre class="screen">
23 f @and @attr 1=1003 knuth @attr 1=4 @attr 5=1 computer
25 Finally using a mix of Bib-1 and GILS attributes could look
27 </p><pre class="screen">
28 f @attrset Bib-1 @and @attr GILS 1=2008 Washington @attr 1=21 weather
