Description Field Not Searchable/Being recognized by Process Definition

Hey All,

Our leads have a Description text field that is automatically populated when leads are created and info is pushed from our ERP.

I've found that some of Description text fields are not searchable. I also tried creating a Sugar BPM rule that changed a field on the lead based on this text field as well. However, they don't seem to be getting picked up.

It seems to be for strings of text that have a "-" with no space immediately after. For example "XYZ-ABC" is not searchable but "XYZ - ABC" is.

Any idea what the root of this could be?

Thank you,

Andrew
