[Proposal ]OR search criteria within performFind

[gil portenseigne]

Hello,

In a customer project we met a very specific need in a search screen 
that offer search criteria that must unions and not intersect.

I propose this improvement in OFBIZ-10195, https://s.apache.org/sjW1 but 
i'm wondering if any of you ever met such need ?

Is that worth to be commited in the code base ? I tend to say yes, but 
i'd like to hear the community out about this.

Thanks !

Gil
