index join without query criteria

[Hari Iyer]

Hi,

It appears that a query criteria is mandatory for a join. Taking this example 
from the documentation: fq={!join from=id fromIndex=movie_directors 
to=director_id}has_oscar:true. What if I want to find all movies that have a 
director (regardless of whether they have won an Oscar or not)? This query: 
fq={!join from=id fromIndex=movie_directors to=director_id} fails. Do I just 
have to make up a dummy criteria like fq={!join from=id 
fromIndex=movie_directors to=director_id}id:[* TO *]?

Thanks,
Hari.
