After hitting C-[ for entering a citation with RefTex, I want to search for an author that has an umlaut (\"u or ü) in the name. Let's say the guy's name is Müller. I tried
Muller
Müller
M\"uller
M{\"u}ller
{M\"uller}
M\"uller
and some others.
all with not a single result. In the bibfile this author is entered as M{\"u}ller (sometimes M\"uller or {M\"uller}) The problem is that this name is very common and also variations of it (like M\"oller) so that just searching for M.ller is not helping.
Can anybody help? Thanks a lot,
Thomas
