AEM 6.2 Search componet using tags

Response from Adobe :

Tag search works on OR condition therefore when you select Tags, it does a search and basis OR condition it fetches all results where either of the tags match.  So, this is the designed behavior. If you need AND condition, you would need to customize it. 

If i add a new param 'group.property.and=true', its returning AND condition results.

Any thoughts on which file I have to customize to add this new param ?

Thanks for your help again.
