Dohn, see my reply to Powers about Google searches, above. I regard these as crucial for our titles to take into account. That is how many web users encounter our articles; Google knows that, and gives our titles great prominence. This is not understood well by WP editors.
I consider the behaviour of WP's own search prompts important, even if these are a second consideration after Google has been taken into account. Under "my scheme" in its completeness, or some scheme that I would accept, one might type as far as "Catholic Memorial" and get a better, more comprehensive DAB page that would include several that are not readily findable now. As things stand, prompts show a couple of DAB pages with identical content (is that kosher?), and two specific article pages: for Massachusetts and Wisconsin. Under the proposal in this RM, it is hard to say how things might go. Not usefully for the reader, as far as I can see.
I regret that because of commitments in the world at large I have little time to take this further (though I have, you will agree, commented in detail already; thanks to you, for doing the same). For me the essential point is broad. I don't really care about individual cases of confusion arising from bad RMs; I would like to see a more sophisticated understanding of titles generally, for our millions of articles. Things are at a low standard right now.
