commit ffee4175991435b18090ca16a1c30449a7784391
Author: sunnavy <sunnavy at bestpractical.com>

    allow to search the string from anywhere in the word
    
    by default, Chosen's search matches starting at the beginning of a word.
    setting this option to true allows matches starting from anywhere within a word.
    This is especially useful for options that include a lot of special characters
    or phrases in ()s and []s.
    
    I believe it's good to be enabled by default
