Query Google.com

Query google.com (in english) without using any API key with the default WebClient class We are also instrumenting google ability to search between certain time period example: querygooglen 500 3000 "F#" 30 Here you fetch for 500 urls (we are grabbing 100 urls by query on google) wait between each query to google.com for 3 seconds you are seeking for the keyword "F#" you only want results who are at least newer than 30 days ago -Nicolas http://hackeratwork.com/
