I would like a mathematical search-thesaurus; this would be a list of descriptions people thought of to use as search terms (and that I might think of using) and for each description, a list of phrases that appeared in documents which contained stuff relevant to the descriptions. A recent example might be: "gently falling curve" yields "roller coaster physics". A prototype of a thesaurus could be built out of the MathOverflow database.
