countDistinct, iterateDistinct, listDistinct and listDistinctResults will be deprecated in Querydsl 3.0 and removed at a later time. This is because the same effect can be achieved with distinct() + count/iterate/list/listResults. This usage is more in line with other result modifiers such as limit, offset and orderBy.

As an example the following query

query.from(...).listDistinct(...)

can then be expressed as

query.from(...).distinct().list(...)

If the listDistinctResults will be removed how the funtionality of select distinct on specific field with pagination can be accomplished? Today the search result also calculates the total rows number on the distinct field

@hamavaro I think you are looking for the GROUP BY clause.
