Currently, AWB's listmaker will only return 1000 results from a wiki search. This can makes assembling larger lists require manual search result processing outside of AWB, since there is no way to fetch the next 1000 results. Performing fixes on the first batch of 1000 and then doing a new search doesn't always work because (a) the search results seem to lag behind after edits are made and (b) some fixes, especially those that modify non-alphanumeric characters, cannot be distinguished from the original text by the search engine.
This presumably dates back to when the API only returned 50/500 results for user/bots. However, now that the API limits have increased to 500/5000 results, it might make sense to expand AWB's limit to 10,000 results (coincidentally, for Wikis using CirrusSearch, 10,000 total results is the most that will be returned using the "continue" function).
This could either be done in AWB core, or in the NoLImits plugin.
