Comment (by enrico.sorcinelli):

 @adamsilverstein The line above is the default value for `options.lower`
 that lowercases the string in the `normalizeQuery` function.

 So if the database is case insensitive, typing `Foo` or `foo` from client,
 the search will return same results: the patch simply prevents to send to
 the server both requests if the user types subsequently two or more
 queries differing only by spaces and/or case sensitive.

 I was thinking that exposing `dbCollate` as a global JavaScript variable
 could be useful in other client situations, even if on the server side we
 can lowercase the keys based on `$wpdb->collate`.
 Anyway, currently, the core
 [[https://core.trac.wordpress.org/browser/trunk/src/wp-includes/class-wp-
 editor.php?marks=1586-1587#L1586|does not]] by default, so we can improve
 also that code.
