If 'iConn.getItemSpocno().trim()' is a blank
and '(iConn.getSpocFAIExclusionList()' = S070,S110,S120,S130 why does the following still return a 0 value?

Because an empty String can be found at the 0 position.
Imagine: if you add nothing to the beginning of that String, it won't change. Therefore it is the same as having an empty String at its very beginning, so you get 0 as the index.

If you will search blank i.e. "" in any String then it index will always be 0.
I agree. Here's the link:
