From the docs:
To set criteria for a view
URL format for setting criteria with "=" (Equal) operator is given below
http://creator.zoho.com/<app owner name>/<app name>/#View:<view name>?<FieldName1>=<FieldName1 Value> &<FieldName2>=<FieldName2 Value>
This allows for criteria of the form <criteria 1> AND <criteria 2> as I read it.
I need the form <criteria 1> OR <criteria 2>. There's other logic operators listed but no OR. Is there some way to use an OR in this situation?
