Hi Florian,
thx for the info.
Yes, on server side I only return 5 hits except for the last page where I only
return 1 (total numItems = 16).
I am just a bit confused about the display in the Chemistry Workbench
QueryFrame:
When I set skipCount to 0 with maxHits = 5 it properly only shows up 5 hits.
But when I set skipCount to 5 it fetches all the pages up to the end and shows
11 hits
[cid:5EA16AC0-7015-4A7D-8690-4F120273DF55]
In the code of the QueryFrame the ItemIterable (variable “page") then
automatically fetches the next page when getting to the end of one page.
results = model.query(text, searchAllVersionsCheckBox.isSelected(), maxHits);
...
ItemIterable<QueryResult> page = results.getPage(maxHits);
for (QueryResult qr : page)
{
// with skipCount > 0 here at every 5th loop the next page is automatically
fetched from server
...
}
...
When I set numItems like Alfresco Demo Server does then it is displayed
properly (Alfresco seems to set numItems to 5 for first page, 10 for second
page and so on …).
But this setting of numItems is wrong when I understood you correctly.
So I am just wondering if I do sth. wrong or this is an issue elsewhere?
tia
Cheers

Hi Sascha,
You are right, totalNumItems should stay the same for each page (assuming that
the data in the repository doesn't change).
Some repositories don't always return a value for totalNumItems, but that's OK
from the spec point of view.
If the client sets maxItems to 5 the server MUST NOT return more than 5 hits.
It may return fewer hits (because there are no more hits or because of any
server constraints), but never more.
OpenCMIS doesn't have a TCK test for that, yet. It may be worth adding one...

Hi all,
I am currently struggling with the paging of a query result set.
Did I understand it correctly that “numItems” should contain the whole
number of items (if the repository knows about it)?
So for example a repository only contains 16 documents all from type
cmis:document and we have a query like:
“SELECT cmis:name FROM cmis:document ORDER BY cmis:name”
When we set the page size (maxItems) to 5 and the skipCount to 0 then
I assume that the server should pass the first 5 results (the first
page) and set the numItems to 16.
When we want the second page we set skipCount to 5 (and leave maxItems
= 5) and still numItems is 16.
Third page with a skipCount of 10 and still numItems = 16. And so on…
Is this correct?
Cause when I do it this way on the server the QueryFrame in the CMIS
Workbench gives me 11 hits for skipCount = 5 and maxItems = 5 (the
ItemIterable in the loop just goes through all pages).
I compared with Alfresco CMIS Demo server. For this the Workbench
QueryFrame properly only shows up 5 hits for every page but it seems
the Alfresco Server does set “numItems” to the summed up number of
items until current page (numItems = 5 for skipCount = 0, numItems =
10 for skipCount = 5).
I strongly assume Alfresco is right here.
