Looks like this does it:
and ($object <http://www.uhi.ac.uk/ontologies/ltk/relationships#isInCategory>
<info:fedora/test_category_1>
or $object <http://www.uhi.ac.uk/ontologies/ltk/relationships#isInCategory>
<info:fedora/test_category_2>)

Subject: [fcrepo-user] grouping itql queries
Hello good folk, I'm hoping this is possible:
Using risearch I can query against a dc:subject as well as being in a category
(collection):
select $object $title $subject from <#ri>
where $object <dc:subject> 'test'
and $object <dc:title> $title
and $object <dc:subject> $subject
and $object <http://www.uhi.ac.uk/ontologies/ltk/relationships#isInCategory>
<info:fedora/test_category_1>
or $object <http://www.uhi.ac.uk/ontologies/ltk/relationships#isInCategory>
<info:fedora/test_category_2>
Problem is the 'or' clause finds all objects in test_category_2 independent of
the subject search. What I need is:
Object has dc:subject='test' and is in either test_category_1 or test_category_2
Is there a way to evaluate:
subject=test and (isInCategory=test_category_1 or isInCategory=test_category_2)
Thanks,
Alistair
