fetchAllResults

public boolean fetchAllResults()

Description copied from interface: Search

Should we fetch all results in the cache thread? Normally, the cache thread just makes sure the results instance exists, but doesn't explicitly fetch any results. For total counts, however, we want the cache thread to actually keep fetching all results, so we can keep track of the total count.

Returns:

true if cache thread should fetch all results
