I think you're a wee bit off course with the idea that spelling is not a problem in a full text retrieval system Philippa. Not only spelling (regional and (in)accurate), but inserted but unprintable ascii characters, and as you demonstrate, multiple synonyms for a song/tune are all major headaches when searching a database like the DT. The use of wild card and phonetic searching algorithms can alleviate the problem but only at the expense of highly unspecific results. Even the use of key words is fraught with problems in the same way eg WW1 is not the same as WWI, politics is not the same as political etc. added to which the attribuion of a keyword is a value judgement not a definitive. So lets not minimise the problems but thank Dick/Susan/Max for the excellent facilites they have provided.Pete M
