We would like to AB test the did-you-mean phrase suggester with the default title/redirect.title configuration vs an extended configuration that also includes the opening_text. To facilitate we need to update CirrusSearch such that it creates a second field and populates it with the appropriate data.

This will require a full-cluster reindex operation, which is actually pending for a number of reasons (various language analysis chain updates, regex trigram indexing changes, etc.)

turns out we did not have this enabled when the recent reindex was run, will need to keep waiting on this.

Ran a reindex last week, can see now we have the suggest_variant field everywhere and should be ready to construct an AB test.
