<p class="MsoNormal">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.<o:p></o:p></p>
