Hi all,
I just discovered freebase and I love it:) Great work!
I have a problem with a MQL query.
Im trying to get the names of the documents with the type
"/military/military_conflict" and "/time/event" within a start and
end date.
I only want the documents without the "included_in_event" property. Or
when it has a "included_in_event" property, the document attached to
the event may not be of the same type (/military/military_conflict in
my example).
Below query dousnt seem to do the trick.
[
{
"/time/event/end_date" : null,
"/time/event/end_date<=" : "1948",
"/time/event/included_in_event" : [
{
"a:type!=" : "/military/military_conflict",
}
],
"/time/event/start_date" : null,
"/time/event/start_date>=" : "1937",
"a:type" : "/military/military_conflict",
"b:type" : "/time/event",
"limit" : 1000,
"name" : null,
"sort" : "name"
}
]
Can someone help me fix this query?
Thanks in advance!,
Regards,
Thimon
