We currently have functionality to search COS by event and session attribute. It will be useful additionally have the same search functionality/criteria as is available in Softlayer:

cookie
Dimension
Free Text
Http Header
Query String
Struggle Score (not a must have)
URL
URL Fragment

This will aid analysts and admins when searching for session expected to be in COS but events or session attributes may be yielding nothing. To be able to search free text as well as other criteria will be immense overall improvement. This will also aid in the use case of purging of sessions from COS when search by event or session attribute will not yield the correct results. This use case will be key when searching/validating any PCI PII issues.
