Sven -- 

I think you should be able to get results you want using "regular expression"
searches on your 'keyword' field.  E.g., the following tags-todo search should
find headings that have both 'career' and 'code-writing' in a 'keyword' property:

keyword={career}keyword={code-writing}

This search would find headings that had one or the other or both:

keyword={career\|code-writing}

Regular expressions start out simple but can get very complex.  I expect there's
a way to get whatever you want out of the "multi-value" property strings you
want to use.
