Search function question

[JimmyL]

Just want to make sure I completely understand our search function. Is it not a one word search engine? I know it will look up a word if I type it in. But if I type in two words, for example "vacuum leak", doesn't it give all things with "vacuum", and all things with "leak", but not all things with both together.
On another forum set up like ours (Chevy or Ford truck. I forget which), you can search for phrases, or multiple words by placing a * after the word, and leaving a space, or putting in a comma........ something like that.
SO, are we one word only?????
