Hi Matt,

I think I undersatnd what you are trying to acheive.  Currently any string searches in the report sql utilise the like sql keyword so within the string parameters you enter when running the report you can use any of the simple string matching patterns which typically use the % character. 

To be able to do more complex functions such as you describe they would need to be incorporated into the reports sql I believe.  I don't believe you can modify the parameter in the sql to include the function but maybe worth trying i.e  In the customer list report you have a where clause

where l.name like $P{classification}

changing to

where $P{classification} 

and including whatever combination of where clauses when you are prompted in the reports classification field i.e  like "breeder%" and like "farm%"

Cheers

Tony
