Idiom for using FullTextQueryImpl with paginatination

iw · **Joined:** Fri Jan 12, 2007 10:44 am **Posts:** 2

I have begun using Hibernate Search (3.2.1 GA)...very sweet.

One issue I encountered was the use of FullTextQueryImpl#resultSize() with pagination.

I would like to obtain the hits count (with #resultSize()) to present to the ui (with #setFirstResult(int) and friends for the pagination).

Should I use #scroll() for initialising the resultSize, and then subsequently call #setFirstResult(int),...#list() for the results?

many thanks,
ian

Apologies, just browsed http://www.hibernate.org/hib_docs/annotations/reference/en/html/lucene.html once more. It has the following...

Quote:

If you wish to minimize Lucene document loading, scroll() is more appropriate, Don't forget to close the ScrollableResults object when you're done, since it keeps Lucene resources.

I will go ahead and use scroll().

thanks,
ian

yes, scroll is what you want.
I should probably introduce some sort of scroll fetch_size to load objects by batch in this case.
