Yeah, certainly. The search might be expensive. Or, some of its resources might be devoted to distinguishing the most relevant among the information it receives - diluting its input with irrelevant truths makes it work harder to find what's really important.

An interpretation of the original statement that I think is true, though, is that in all these cases, receiving the information and getting a little more knowledgeable offsets the negative utility of whatever price was paid for it. The negative utility of the combination of search+learning is always negative because of the searching part of it - if you kept the searching but removed the learning at the end, it'd be even worse.
