Mysql MATCH AGAINST IN BOOLEAN MODE not working properly

Question

In Mysql, I have items table with Title Column in it. Of course, I added FullText Index to Title column.

When I try this query,

SELECT * FROM items WHERE MATCH (Title) AGAINST ('#26' IN BOOLEAN MODE);

It returns no results.

But when I try to do,

SELECT * FROM items WHERE Title LIKE '%#26 %';

It returns me correct results, for example,

• 2018 Topps Living #26 Yoan Moncada Rookie RC Gem Mint BGS 9.5
• 1986-87 Fleer Basketball #26 Clyde Drexler RC Rookie HOF Mint PSA 9

It's making me more confused because following MATCH AGAINST queries works fine

SELECT * FROM items WHERE MATCH (Title) AGAINST ('RED' IN BOOLEAN MODE);
SELECT * FROM items WHERE MATCH (Title) AGAINST ('#269' IN BOOLEAN MODE);

Of course, I changed ft_min_word_len = 2 in mysql config.

Can anyone help me with this?
