Howto combine two loops with "anti-doublons"

The documentation of {doublons} explains how this criterion, like {unique}, enables you to exclude some elements from the results of a query.
However, {doublons} can do much more than that : like {unique}, it stores in an array the results from successive loops. But, with {doublons}, this array can be re-used later in another loop, thanks to a special criterion : {!doublons} (named "anti-doublons")
Example :
BOUCLE2 displays in a chronological order the titles of the articles that are either tagged with the keyword number 2, OR that has been writen by the author number 1.

<BOUCLE2(ARTICLES){par date}{!doublons A}>#TITRE<br></BOUCLE2>
