Problem with regular expression

hi,

i have problem with regular expression in php..
suppose i want to create a search facility..
when user entered, for example : "artist+korean+pop",
it will begin a search using these 3 words as a keywords.

My problem is.. i don't know how to form a regular expression that match these criterias...
For that example, i will form "(artist|korean|pop)+(artist|korean|pop)+(artist|korean|pop)+".

Very silly heh? if there're 10keywords, it will grow too...
could somebody help me,plz...

Why dont you match inidividual strings in a loop

$strs = split(" ", "artist korean php");

for($i=0;$i<sizeof($strs);$i++)
{
//match pattern with $strs[$i];
}

that's not what i want..

the pattern "artist+korean+pop" means :
1. these string : "artist korean pop" is match.
2. string : "korean artist pop" is match too!
3. string : "pop artist korean" is match too!

i bet your solution just worked for the 1st possibilities,right?

thx anyway..

that's my problem!

i think it is very silly to create a looping for thing like that..
cause there'll be too many possibilities..
there a simpler approach, right?
by using regular expression...
