You need to learn regexp. Have a look at M-x re-builder. 

To match WindowsMemoryCacheManagement you don't need
.*m.*e.*m.*c.*a.*c.*h.*e.* at all. The pattern \w*mem\w*cache\w* would
find that string. Note also that emacs isearch (C-s) is an incremental
search in the sense that if you start by typeing 'mem' it will match all
words in the buffer with mem in them, typing the next character i.e. 'o'
will match all with memo etc. Using the regexp version means you can add
regexp patterns. So, in the above case, I would type memoryc or
mem\w*cache, which would match the string you want.
