Searching for String yields different search results compared to [Char]

[Flogex]

When searching for String->[String], I can find results such as lines or words. But these results do not appear when I search for [Char]->[[Char]] although it should be synonym.

They are synonyms - but that doesn't mean that Hoogle treats them as interchangable. It's meant to try and treat them as pretty similar, but not identical, and the current type matching is still undergoing tweaking. I'll take this as another case to look into.
