Comment 4 for bug 632363

I am trying to find out where we should start. Since the "OR" conditions appear when we have more than one event template. This means we need to handle the issues in _build_sql_from_event_templates in main.py by somehow decomposing the event components.

Until now we build sql template code for EACH event independently. Which makes IMHO this issue is more complex than I thought. The above examples require us to have 2 event templates where only the interpretations are different, however what if several event properties are different?
