regular expressions and multiple match

hi,

let us search a.+b in string abcabcabc

var reg = /a.+b/g;
var tab = reg.exec("abcabcabc");

document.write(tab[0]);

there are 2 possible matchs:

abcab
abcabcab

javascript choose the second one. Why not. But what is the rule ?
Does javascript always provide the longest possible match ?

If i want abcab, is there something to do ?

thx
