The problem is:
"Find" useless in searching files by part of filename:
We use filenames alike AAAA_BBBBBB_CCC-DD.ipt (AAAA_BBBBBB_CCC-DD.iam)
where:
A - letter
B, C and D - digits

for example there is file ITEA_758491_002-01.ipt placed in Vault
But it won't be find using criteria {"File name" + "contains" + "491_002"}
Criteria {"File name" + "contains" + "ITEA_758491_002-01"}

Looks like the hot fix for the issue is needed.
