I m new to Yahoo websearch api. trying to get number of search results for a set of query and pass it to my math module (using total_results_available). I need a variable which indicates the cardinality of the set of web pages indexed by Yahoo, in other words, the total number of web pages Yahoo api looks for before returning me the result. could anyone provide me any help/suggestion where i may find that value? and how often it gets updated? greatly appreciate any kind of help!!! thanks guys!
