'''var response = await \_client.SearchAsync(s =\> s  
.Index("indici\_timeline\_death\_patient\_vector\_ml")  
.From(0)  
.Size(10)  
.Query(q =\> q  
.Bool(b =\> b  
.Must(m =\> m  
.Term(mu =\> mu.Field(f =\> f.patientid).Value(formData.PatientID)),  
m =\> m.Term(mu =\> mu.Field(f =\> f.practiceid).Value(formData.PracticeID)),  
m =\> m.Terms(ts =\> ts.Field("eventtypeid")  
.Terms(new Elastic.Clients.Elasticsearch.QueryDsl.TermsQueryField(formData.EventIDs.Select(id =\> FieldValue.Long(id)).ToArray())))  
)  
)  
)  
);  
}'''  
Here is my code. And i am using Elastic.Clients.Elasticsearch library.  
i made three queries in must clause and i want that:  
1: When i send Patiendid , Practiceid and "empty" Search then the data should be showed on PatientID and PracticeID.  
2: When i send Patiendid , Practiceid and "wrong" Search then nothing should be showed. No Patiendid , no Practiceid and no Search.  
3: When i send Patiendid, Practiceid and "correct" Search then the data should be showed according to them.  
That is why i keep these three quires in must but i do not know how can i achive this thing . I hope you understood my scenario. I will wait of you replay . Thank you very much.`Preformatted text`
