There is one gotcha with this function. For backwards compatibility, I haven't included a UniqueValues ( ) check on the needles value list - which means that duplicate values in needles leads to double counting, i.e. PatternCountValues ( "123¶234¶235" ; "123¶123¶234" ) will give the answer 3. For 16 & 17 users, use:
// PatternCountValues ( haystack ; needles )
searchterms = ValueCount ( needles );
needles = UniqueValues ( needles ) // prevents double counting
haystack = "" ; 0 ;
searchterms = 0 ; 0 ;
searchterms = 1 ; PatternCount( haystack ; needles ) ;
