Fixed to show files in deepest directory in search results

Fix: #206595

I have confirmed that it appears in the following way.

1. execute the following command in an empty directory
2. search for searchbox in Hello

 mkdir -p Foo/Bar
 echo Hello > Foo/foo
 echo Hello > Foo/hoge
 echo Hello > Foo/Bar/buz
