Use the Right Search Set for the Job
DEVONagent allows you to search not just using Google, but with many more specialized search engines. For serious web research, you should use this possibility. Choose the search set that best suits your needs instead of just using the default 'Internet (Fast Scan).' To choose another search set (a parameter set for the next search run), select it from the little magnifying glass pop-up in the search field.
And if you need something more specialized for your research, e.g. when you're often searching for patents or in some less known blogs? Then make one yourself: Choose 'Edit Search Sets' from the mangifying glass pop-up and create your own search set.
