eDiscovery KeyQL

I am hoping someone might be able to help me with some KeyQL syntax. I want to find documents that contain a combination of SITs with a minimum occurrence of 1 and a confidence level of between 85 - 100%. I have used the following syntax which shows no errors before I run the query. I have tested the first Sensitive type using the condition builder and it returns matches but even if I try the first line of KeyQL on it's own nothing is returned. Could anyone help please

SensitiveType:“50b8b56b-4ef8-44c2-a924-03374f5831ce” |1..|85..100 - Microsoft built in SIT "All Full Names"
AND SensitiveType:“accaf4c2-fb54-40f7-aea8-db0e36a2e9eb” |1..|85..100 - Custom SIT "DOB"
AND SensitiveType:“8B9E5FBC-4AA9-4017-8256-BE3E8241AEB5” |1..|85..100 - Microsoft built in SIT "U.K. Physical Address"

Thanks
