I'm not suggesting to deal with OR clauses. I tried to manipulate serversql
in OnBeforePrepare event and recognised that IBO detect my additions, set it
into brackets and adds search criterias, e.g.

IBO delivers first: 'where search_criterias'
I set in OnBeforPrepare: 'where ( search_criterias OR MyCondition )'
IBO delivers next time: ' where ( search_criterias OR MyCondition ) AND (
search_criterias )'

Here is IBO too smart for my needs :)

Mit freundlichem Gruss & Best Regards
