can not get multiple matches using regex

[bhomass]

I am using GWT Regex

RegExp regExp = RegExp.compile("\\b" + searchWord + "\\b", "gi");

        MatchResult matcher = regExp.exec(input);

this only returns the first match. why is that? I already set the global option. any one knows how to get multiple match return?

Call exec() again with the same 'input'. See the bottom of https://developer.mozilla.org/en-US/docs/JavaScript/Reference/Global_Objects/RegExp/exec

in that case, what is the point of matchResult.getGroupCount()? it is always 1.

Groups in regexps are those things between parentheses. In "a(b+)c" matching against "abbc", there would be 2 groups, the first one (group 0) would be "abbc" while the second one (group 1) would be "bb".
