Hi:
    Thank you!  yes, there is not  any email in Tracker at all. because it returns "Results:0",  how should i  index the email in Tracker? i didn't known why there is not any email in Tracker, but there are many emails in Evolution.   
    i type "tracker-stats" and   the information is as following:
     Statistics:
     mfo:Action = "">     mlo:LandmarkCategory = 15
     mto:State = 9
     mto:TransferMethod = 2

    scal:RSVPValues = 2
    scal:TodoStatus = 4
    scal:TransparencyValues = 2
    tracker:Namespace = 21
    tracker:>



    i can search softwareApplication  by API which libqttracker supports. example:
       RDFVariable query_result = RDFVariable::formType<nfo::SoftwareApplication>().property<nie::title>();
   
    am i right?  who can give me  some suggestions?

I see, this works for me:

tracker-sparql -q "SELECT ?s WHERE { ?o nmo:to ?s ; nmo:messageSubject
\"Meeting Friday\" . }"
Result: 1
 urn:uuid:0b31ef4e-36a6-0220-6cd7-1c22efae3d54

Do you have any emails in Tracker yet? You should see a list of emails
if you use this:

tracker-sparql -q "SELECT ?s nmo:messageSubject(?o) WHERE { ?o nmo:to ?s
. }"
