To sort on Bib1 attribute title, case insensitive, and ascending you
|
|
would use the following sort criteria:
|
|
<div class="example-contents screen">
|
|
<div class="examplescode"><pre class="examplescode">1=4 ia</pre>
|
|
</div>
|
|
</div>

</p></div>
|
|
<div class="example-contents"><p>
|
|
If the secondary sorting criteria should be author, case sensitive and
|
|
ascending you would use:
|
|
<div class="example-contents screen">
|
|
<div class="examplescode"><pre class="examplescode">1=4 ia 1=1003 sa</pre>
