No, actually, ^ and $ define the beginnning & end of the entire
expression being searched, not the boundaries of a single
word. Therefore searching for ^mouse$ will locate "mouse" only if
it's the only word in the entire string, which I gather is not what you want.
I suspect what you want is either this:
(^| )WORD( |$)
(the word bounded by either the start/end of string or a space)
or perhaps better yet this:
\bWORD\b
(the word bounded by word boundaries).
See [PCRE regex] Pattern Syntax

Further to your problem, I believe this is incorrect:
$noiseArray = array("1", ...
...
$searchQuery=str_replace( "^".$noiseArray."$", " ", $searchQuery);
Since $noiseArray is your entire array, it doesn't make sense to
enclose it in word boundaries of any kind. Instead, I imagine each
member of the array needs to be bounded individually.
If you go this route, perhaps you could enclose each member of your
original array in \b word boundary sequences using an array_walk
routine so that you don't have to muddy your original array
declaration statement.
