That's what I was thinking, but I also just read in some documentation (https://docs.microsoft.com/en-us/azure/logic-apps/workflow-definition-language-functions-reference#contains) that this function is case sensitive. So, that makes I actually need to check and see if one of four different possibilities is true.
Basically if string contains
Today AND Blue
OR
Today AND blue
OR
today AND Blue
OR
today and blue
So would that mean I needed the following operation?
@or(and(contains(triggerOutputs()?['body/content_excerpt'],'Today'), contains(triggerOutputs()?['body/content_excerpt'],'Blue')), (and(contains(triggerOutputs()?['body/content_excerpt'],'Today'), contains(triggerOutputs()?['body/content_excerpt'],'blue')), (and(contains(triggerOutputs()?['body/content_excerpt'],'today'), contains(triggerOutputs()?['body/content_excerpt'],'Blue')), (and(contains(triggerOutputs()?['body/content_excerpt'],'today'), contains(triggerOutputs()?['body/content_excerpt'],'blue')))
