How to implement sublime text like fuzzy search?

Question

How can i implement a sublime-like fuzzy search on select2?

Example, typing \"sta jav sub\" would match \"Stackoverflow javascript sublime like\"

Answer 1

select2 allows you to implement your own "matcher" functions (as seen on their docs), using that and some regexp you can do something like:

$("#element").select2({
    matcher: function(term, text, opt) {
        //We call to uppercase to do a case insensitive match
        //We replace every group of whitespace characters with a .+
        //matching any number of characters
        return text.toUpperCase().match(term.toUpperCase().replace(/\s+/g, '.+'));
    }
});

A matcher function is invoked against every select2 list element when filtering / searching the list, you could implement any kind of custom search using that.
