Hello,
I have by mistake duplicated the score "C'est lui que mon coeur a choisi", by Max d'Yresne and Raymond Asso.
The reason is that my search was as follows:
I first typed the whole title: no answer.
Then, as I often do, I limited myself to "It's him".
And there, two answers, but not the right one ("It's him" and "There is only one it's him"). "That's" what fooled me, having deduced that mine wasn't there.
Slade will surely be able to enlighten me, but I think the apostrophe might be responsible (multiple coding?). By the way, if you type all or part of the title without "it's" ("chose" is enough, for example), you get the right result.
You can also, of course, enter the name of one of the authors.
With the first name if necessary (for example "Asso" without Raymond, in this case, is part of too many words and names to lead to an efficient search: 13 pages of results, from Cassonet or Masson to Gloria Lasso through Massoti, Nekrassov and many others).
The problem is perhaps not soluble.
So should we be wary of the apostrophe in searches?
And are there other problematic characters?
