A post in the Local Search Forum notes that earlier this week, the Google Maps search results showed 20 search results per query, now it is showing only 10.
The user said "I noticed today that Google Maps are showing 10 results per page again. Not sure for how long, but up until Monday, there were 20 results per page." Adding that there is now "shorter result pages, there are slight changes to the search box too and photos are back."
