Improve the pinyin fuzzy search function

1. Please look at the following two pictures, the same search keyword, using the initial letters of Chinese pinyin, can only match one of the files, the other is not displayed. If you use full spelling, or a mixture of simple spelling and full spelling, it can be displayed normally.

2. Also, for keywords with spaces in the middle, do not match in the order of all keywords, and if they cannot be matched in order, match them in sections to the file name section. Because some file names are very long, I only remember a part of them, and I need multiple keyword matches, but I don't remember the order of the keywords in these file names. (This feature was mentioned in one of my previous requirements).
