When searching using Spotlight for, say, the word "Exotic", it fails to report the file Important_Exotic_Class.h, containing a C++ class by that name.
Can you think of a method to make Spotlight index the portions of identifiers between underscores in .h and .cpp files? In the example above, the three words would be indexed.
Even just indexing the words between underscores in filenames would be very useful.
