Hey this is pretty awesome, thanks! I tried it with several libraries using different formats, it worked pretty much flawlessly, and the interface is quick and slick. I have a question, what are the semantics of surrounding a search query in quotes? E.g. if I search for "default constructor" I get pretty much what I expect, but searching for "mutable" also produces things like "MutableBufferSequence". It seems to me quotes are ignored if the query has only one word? Anyway, it may be better if using quotes finds exact matches only. Obviously this is a very minor thing. Another question, how does it handle different Boost versions? E.g. what if a function is removed, it would be nice if it doesn't dig it up from some old version of the library. Overall it looks great!
