Hi Nick,

This scenario you describe is possible be made by custom query

https://docs.umbraco.com/umbraco-cms/reference/searching/examine/quick-start#creating-the-search-query

string drop1Value = "test1"; //or another type you are using
string drop2Value = "test2"; //or another type you are using

if (_examineManager.TryGetIndex("ExternalIndex", out IIndex? index))
                {
                    var result = index.Searcher.CreateQuery("content").NodeTypeAlias("myDocumentAlias")
                       .And()
                       .Field("property1", drop1Value)
                       .And()
                       .Field("property2", drop2Value)
                       .Execute();
                }

Something more or less like this. If you need more help, show the code
