Regex match in javascript

I would like to match the following term in JavaScript using regex.

String = 'abc AND def AND igk AND lmn'

Terms to match: the word before and after first AND.

For example in the above string the match part will be : abc AND def.

I want to do it in JavaScript. So I will call 

string.match(/regex to use/)

and assign it to a var.

Any suggestions please.

EDIT:

the string can be of form like:

    string = 'AND abc';
    string = 'abc AND';
    string = 'abc def AND igk lmn';
    string = 'abc def AND';
    string = 'AND igk lmn';

Appreciate your help in this regard.

You can try this regex:

/(\w+\s+AND\s+\w+)/

EDIT (after having read your last update): if left and right terms are optional, use the following regex instead:

/(?: (\w+) \s+)? AND (?: \s+ (\w+))?/x

A slight improvement on Igor's version : 

   var m = str.match (/(\w+)\s+AND\s+(\w+)/);
   // word before AND in m[1], word after AND in m[2]

Automagically extracts the two words.
