Search function on chef talk

I don;t know if i made this comment somewhere but it's probably the main problem i have with the workings of the site, which are pretty good over all. 

If i do a search i can't use the usual quotations, AND OR or other what do they call them, Boolian functions. 

If i put "chocolate cake" even with quotes, i get everything with chocolate and every cake. 

I find that if i want to find something on cheftalk, i have to go to Google and put in "cheftalk" "chocolate cake" if i want to actually get a chocolate cake recipe on cheftalk.  (of course chocolate cake is just an example, and would be too vast a search anyway, but say, i want to find if i posted my recipe for gnocchi di zucca so i put "gnocchi di zucca" OR "pumpkin gnocchi" OR "squash gnocchi" i get every gnocchi recipe, every squash recipe, etc. 

It's particularly annoying because when someone asks a question and it's been treated before, someone will always say, and you can often hear the annoyance coming out through the words on the screen, that it';s already been asked on this site and do a search.  GOOD LUCK!  that's not a helpful answer, first of all, and it's not possible to actually do a search using the search function. 

Or if there is, i don;t know how, and maybe most others don;t know how. 

Can something be done about that?

thanks

Hi Nicko,

The problem arises often when i want to post something and don't remember if i already have, or if someone else has and i haven't seen it.  It frequently happens that someone comments with a very annoying "this was treated in another thread - look it up."  Well, good luck.  I usually can't find anything.  So yes, i guess we could tag threads, but actually i have no idea how to do it, it would rarely occur to me if i did, and anyway, if nobody ever tagged the thread that i'm being told to look up, how will i find it?   

Can't a boolian search function be inserted into the search option?
