I bought IAW a day or two ago.
I've just been trying things out, and found that IAW has real problems with Bing searches.
For instance, when i searched for cats, oranges and pumpkin (separately) on Bing, i got no results. I'd expect these to get lots of results, especially since i could search the same terms with Bing on my browser and get several million results.
Given not all of these would be good material, i'd still expect IAW to return the maximum results (in Custom Settings).
The reason i used Bing is i started to get lots of captcha prompts and related errors on Google, making IAW unworkable. I may pay up to DeathByCaptcha, but not until i've been able to evaluate IAW more.
When i was able to search on Google, oranges returned 33 - whatever that number is supposed to indicate - along with results for about the same number of 'related' key words.
What does the frequency number mean? It doesn't mean number of individual articles, since that seems to be the maximum results i'd set (100). It doesn't mean the number of times the keyword appears in the research, since that would be way more than 33.
Whatever the case, i'd like to see searches on Bing return results similar to Google in quantity. Particularly as it's an alternative to Google when the captcha challenges come up.
