I am currently working on haystack search in django. I met 2 problems, first, when I use 'Whoosh' engine, the search can only return the result that match exactly the same with my search key, for example if I type 'ABC', it cannot match 'ABCD' Secondly, how can I achieve wildcard search using haystack? For example, if I type'A*C', it can return 'ABC', 'ABCCC' 'AC' and so one. Or other method just to achieve the same result(Basically, return the result that contains the key word in same order)
