Describe the bug
When a file is tagged, strawberry doesn't seems to use filename in search.

I have several album from different non latin countries.
I like having the tags set with original characters but to avoid problems to copy to physical player or other support and not have to remember how to use IME to type foreign character, I usually set transliterated names in the *SORT tags and in filename/directory

To Reproduce
for instance, for a file containing Japanese tags:

names	ID3v2.4	values
TITLE	TIT2	歌
ARTIST	TPE1	歌手
ALBUMARTIST	TPE2	歌手2
ALBUM	TALB	アルバム
COMPOSER	TCOM	作曲

I set transliterated version in the following tags

names	ID3v2.4	values
TITLESORT	TSOT	Uta
ARTISTSORT	TSOP	Kashu
ALBUMARTISTSORT	TSO2	Kashu2
ALBUMSORT	TSOA	Alubomu
COMPOSERSORT	TSOC	Sakkyoku

and also use transliterated in directory/filename:

[examples.zip](https://github.com/strawberrymusicplayer/strawberry/files/13628159/examples.zip)
Alubomu
└── Kashu
    ├── '01 - Uta.wav'
    ├── '02 - Uta.flac'
    ├── '03 - Uta.ogg'
    └── '04 - Uta.mp3'

strawberry show correctly theses files in my collection but if I search 'Uta', 'Kashu' or 'Alubomu' I dont get any result. I have to type the characters as they appear on the tags '歌', '歌手' or 'アルバム'.

Expected behavior
Having the song appear in result when searching with original characters or transliterated one

If applicable, add screenshots to help explain your problem.
Is it possible to add the *SORT tags to the search result or at least use file/directory name?
