Jukka Zitting commented on JCR-989:
-----------------------------------
Nice work!
I'm not 100% sure if we should place JCR 2.0 extensions in jackrabbit-api,
after all they are still subject to change and it might well be that the
interfaces will change before JCR 2.0 is final. Putting the extensions in
jackrabbit-api implies that we are ready to offer backwards compatibility to
these new methods even if JCR 2.0 decides to drop them or implement them in
some other way. More on dev@ in a moment...

> In our application we have a search which only shows part of a query result.
> We always know which part of the result needs to be shown. This means we know
> in advance how many results need to be fetched. I would like to be able to
> programmatically set resultFetchSize to minimize the number of loaded lucene
> docs and therefore improve the performance.
> I know it is already possible to the set the resultFetchSize via the index
> configuration, but this number is fixed and doesn't work well in environments
> where you use paging for your results because if you set this number too low
> the query will be executed multiple times and if you set it too high too many
> lucene docs are loaded.
