Hi, Ryan.
I think you should use Filter option of bindRows method. Something like the following:
var oFilter = new sap.ui.model.Filter("query_field", sap.ui.model.FilterOperator.EQ, "query_value");
oSearchTable.bindRows("/SearchLotSet", null, null, [ oFilter ]);
where "query_field" is the name of the field you want to use as a filter and "query_value" is the value of "query_field" for filter.
You can use multiple filters. Just pass them to bindRows method separated by commas, for example, ( [ oFilter1,oFilter2, oFilter3 ] )
Hope this helps.
