Where are you getting that information? I took Aud Q2 (new changes) and it had the search capability. Unless something changed, I think it's still there.
What prep are you using? Both Becker and Ninja have decent simulators for the research questions.
Also – aicpa.org has actual sample tests with a good representation of the real environment that you can use for practice.
Here's a strategy I shared for research questions.
Step 1: analyze the question – what exact word or short phrase (2 to 3 words) do you need to research?
Step 2: go to the “advanced” tab and search “exact terms” (I forget the exact wording they use) but there's an “all words” and I believe “exclude words” and I think even exact phrase. I think the “all words” one is the best.
Step 3: There should be a reasonable number of results that you can now scan through. If not, then step 4.
Step 4: If there were too many results – think of a refining word in the question and add that.
Step 5: If there were no results, think of your search words and think of synonyms to those words that may appear in a codified doc.
