[Zope-CMF] How to limit results in AdvancedQuery

[Dieter Maurer]

Please do not post HTML mail.

Usually, I do not read them at all.
This time, I made an exception as the subjects indicated that it
concerns "AdvancedQuery". It is not sure that I make another exception.

"AdvancedQuery" performs incremental sorting (when it is worth it).
Therefore, there is not need to limit sorting.

Just access as many elements as you need.

If the sort index is sufficiently small compared to the result set,
then AdvancedQuery does not sort more than necessary.

Otherwise, sorting time is by far outweighted by the lookup time
for the document sorting keys. Thus, limiting the sort has an
almost negligible effect.
