Hello theo.
Indeed, by entering Groscolas, you get the score of Lady Lay. However, if you search for "In a month or in a year" by Pierre Groscolas, the search engine will not return anything. It will be the same if we ask for "Lady Lady Lay". In the first case you would have to enter "Grocolas" because this name has been accepted as a composer in the database, in the second it is not the exact title. All this to confirm what I have already written: the "search" function, which is sorely lacking on the home page, is far too discriminating, hence the flood of inappropriate requests.
