Right now we can search "Attachment Name" only by:
"is equal to" or "not equal to"
So there is a need to know exact file name.
It would be great if there was possibility to search "Attachment Name" by partial name also.
For example if I have a lot of messages with invoice files: invoice01234567.pdf, invoice9422145.pdf, invoice67543423.pdf, etc. - it should be possible to get all of these messages that have attachments that contains "invoice" in their name.
In BMA advanced search section there are a few options that allow search with "contains" type ... for example "Entire Message" (but it doesn't include attachments) - why not to allow this in "Attachment Name" also ?
