Until yesterday a query such as this http://autoc.finance.yahoo.com/autoc?query=a&callback=YAHOO.Finance.SymbolSuggest.ssCallback yielded a long list of fuzzy/broadmatch results for both ticker and company name.
Since today you are a.) required to specific region and language and b.) it is only yielding exact match results only for the ticker and not for the company name. Thus usually you get only one results back.
Thus for http://autoc.finance.yahoo.com/autoc?query=y®ion=US&lang=en&callback=YAHOO.Finance.SymbolSuggest.ssCallback there's now only one result: YAHOO.Finance.SymbolSuggest.ssCallback({"ResultSet":{"Query":"a","Result":[{"symbol":"A","name":"Agilent Technologies Inc.","exch":"NYQ","type":"S","exchDisp":"NYSE","typeDisp":"EQUITY"}]}});
Any idea how to a.) broaden the match type and b.) include the company name as the searched field?
