How do I do a Google scholar batch search, and get only the number of results back?
I have a large list of things I want to search for in scholar.google.com (a list of chromosomal r开发者_运维知识库egions), and I only want to the number of results for each search term. Does anyone know what the best way is to do this?
You can use this ruby script
#!/usr/bin/ruby
require 'net/http'
require 'uri'
def number_of_results(search_query)
url = 'http://scholar.google.com/scholar'
query = '?hl=en&btnG=Search&as_sdt=2001&as_sdtp=on&q='+search_query
url = URI.parse(url)
page = Net::HTTP.new(url.host).get(url.path + query).body
if page =~ /of about <b>([0-9,]*)<\/b>\./
return $1
else
return nil
end
number_of_results(ARGV.join(' '))
and call from terminal/console search.rb search term
and if you have array of terms
['foo','bar','baz','quux'].each {|term|
puts number_of_results(term)
}
