I have a set of search queries in the size of approx. 10 millions. The goal is to collect the number of hits returned by a search engine for all of them. For example, Google returns about 47,500,000 for the query "stackoverflow".
The problem is that:
1- Google API is limited to 100 query per day. This is far from being useful to my task since I would have to get lots of counts.
2- I used Bing API but it does not return an accurate number. Accureate in the sense of matching the number of hits shown in Bing UI. Has anyone came across this issue before?
3- Issuing search queries to a search engine and parsing the html is one solution but it results in CAPTCHA and does not scale to this number of queries.
All I care about is that the number of hits and I am open for any suggestion.
