One thing that has always irked me about the present-age search engines are when I type in a query and it instead returns the results for what it "thinks" that I mean. Kagi, unfortunately, seems to maintain this characteristic of software attempting to be smarter than the user. It'd be nice if this was a setting that users can toggle instead of it being the assumed default.
At the very least, the setting would toggle whether to show the results of the specified query and "Do you mean"-link to Kagi's corrected query, with the setting's other value correcting the user's query and informing them of the reasoning behind the query being changed. If adding another setting is considered undesirable, for some reason, perhaps Kagi could complain to the user about there not being not enough results whilst concatenating the few-to-none results for the specified query with the results from Kagi's corrected query? Either would be fine, as long as it's easy to distinguish the number of results returned for both.
