SELECT * FROM catalgo_auto_productdetails  WHERE product_name like '%htc%'

    As documented under Fine-Tuning MySQL Full-Text Search:

    The minimum and maximum lengths of words to be indexed are defined by the innodb_ft_min_token_size and innodb_ft_max_token_size for InnoDB search indexes, and ft_min_word_len and ft_max_word_len for MyISAM ones. After changing any of these options, rebuild your FULLTEXT indexes for the change to take effect. For example, to make two-character words searchable, you could put the following lines in an option file:

    [mysqld]
    innodb_ft_min_token_size=2
    ft_min_word_len=2
    

    Then restart the server and rebuild your FULLTEXT indexes. For MyISAM tables, note particularly the remarks regarding myisamchk in the instructions following this list.
