Search Component - filter by a field value on model

Hey Mark! Thanks a bunch! This worked perfectly. I dont think I woulda been able to figure out the right XML myself. For the record I needed my search component to search only contacts related to the account detail I was viewing. The XML is:

<conditions> <condition type="modelmerge" value="" field="AccountId" fieldtargetobjects="Account" operator="=" model="SelectedAccount" enclosevalueinquotes="true" mergefield="Id" novaluebehavior="deactivate"/> </conditions>
