Hello to all,<br>
A quick question re: classification metadata. In a historical corpus
of medical case studies, it would be nice to include classification
information on the field of medicine concerned. However, in many
cases, several fields are involved. The solution to this might be
just to indicate field_1, field_2, field_3, etc., but this makes
restricted searches a little unwieldy. I was wondering if there is a
more elegant way of doing this, something like just one field, with
boolean alternatives i.e. "neurology|gastroenterology|neurology",
for a fictitious case involved these three fields,
"neurology|gastroenterology" for a case involving just there two
fields, etc.<br>
I hope this makes sense. Thanks in advance for any assistance.<br>
Best wishes,<br>
Graham.<br>
