maxItems parameter?
It is my understanding that there is an optional "maxItems" for (at
least) searching in the CMIS standard?
A quote from something I read: The CMIS specification defines the
maxItems parameter as “the maximum number of items to return in a response”.
I believe this is different than "MaxItemsPerPage" in our OC properties.
But the actual question is whether this is supported/available in
DotCMIS (or OpenCMIS)? I expected it to maybe be in the OC, but it's not
there. Checked if there's an overloaded session.Query() method, but it's
not there either.
Is this available???
Thanks,
AJ

That's basically the same.
This should give you the top 10 hits:
session.query(...).skiptTo(0).getPage(10)

OK, that answers the question I asked.
What I am really looking for is a way to tell the service the maximum number of query results I want returned in sum-total.
Basically a way to pass a query optimization hint like "RETURN TOP".

Hi AJ,
Yes, that is supported by OpenCMIS and DotCMIS.
You control the maxItems parameter with the getPage() method and the
skipCount parameter with the skipTo() method.
To get the first 10 hits call this:
session.query(...).getPage(10)
To skip the first 3 hits and then get a list of max 100 hits call this:
session.query(...).skiptTo(3).getPage(100)
The corresponding JavaDoc is here:
https://chemistry.apache.org/java/0.13.0/maven/apidocs/org/apache/chemistry/opencmis/client/api/ItemIterable.html
