This is a common error when searching ICSD, so no need to apologise :-)
Many people over-restrict their search by specifying too many conditions.
In general you should avoid assuming you know the symmetry, or worse the
space group.
Searching on just ABX6 with 3 elements will give only 157 results, a small
enough number to look at; almost all are halides and most are rhombohedral,
with only a handful tetragonal.
