#39041 closed defect (bug) (fixed)

Installed themes search displays theme author names when the search term is a space

Go in the themes screen and insert a single space in the search field: the theme author names will appear in the theme thumbnails:

Theme author names are intended to appear just when the search term matches the author name. Side note: wondering how many users are aware of this "hidden" feature.

Looking a bit into theme.js, turns out that thanks to this replacement:

term = term.replace( / /g, ')(?=.*' );

the regular expression
match = new RegExp( '^(?=.*' + term + ').+', 'i' );
match = new RegExp( '^(?=.*)(?=.*).+', 'i' );

so it matches any author name and it is longer than 2 characters:

if ( match.test( data.get( 'author' ) ) && term.length > 2 ) {
	data.set( 'displayAuthor', true );

Without changing the regex, maybe the best option would be using jQuery.trim( term ) (because IE 8 is still supported) and then if the term is empty, just return early. Also, I'd like to quote @azaozz and recommend that this kind of searches should fire after a minimum number of typed characters, see:

ideally it should trigger after 2 ASCII chars or one high UTF-8 char. We can standardize this for all similar cases in core, there are at least 6-7 other places.

  • Keywords good-first-bug needs-patch added
  • Milestone changed from Awaiting Review to Future Release
  • Version set to 3.9

Just tested this out on the latest version (5.1.1 as of this post) and this bug is still happening.

Worth noting that IE 8 is no longer supported (only IE11 and newer)., so that is no longer a consideration when solving.

I think we could .trim() the term before finding results. .trim() is supported by all browsers (IE 9+).
