Octoparse allows you to enter a list of keywords to be searched through in a search box and extract the output result of each search.
(Check out the complete tutorial of how to extract the results after searching keywords

If you’d like to capture the search keywords entered as well, it can also be easily done by Octoparse:
After you’ve configured entering a list of keywords in Octoparse, click the search box and select “Extract the text value”, and then searched keywords would be automatically extracted. Isn’t it simple?
