Discover should be able to handle a numerical comma in a title. We received a patron complaint that they couldn't find the title 20,000 Leagues under the sea. They were searching (correctly) with the comma in "20,000" (see this search: https://ada-lynx.na3.iiivega.com/search?query=20,000%20leagues%20under%20the%20sea&searchType=everything&pageSize=10). When searched as "20000", all the results properly come up (see https://ada-lynx.na3.iiivega.com/search?query=20000%20leagues%20under%20the%20sea&searchType=everything&pageSize=10). This is very difficult to explain to both the public and to the staff when our old PAC gives results to that without issue.
