FullText Search - Substring match, possible?

Hi

I am using fulltext searches as search mechanism on an application, I would like to make user experience better, Following 2 steps can make a huge difference.

1.
The user should be able to search sub-strings.
e.g. a model-> Sony WT13i.

Present case -> if a user types wt, he/she can see the results(which includes wt13i)
But if a user types 13i, nothing is returned in the result set.
I wanna show user WT13i even when 13i is typed and searched.

How to implement it optimally?

2.
I do not have a mechanism of ordering the results, from a db/table, according to relevance. i.e results which have +A +B should come before results which have A or in them, A and B being the searched strings.

what is the best practice to order the results, in big databases, which have >50000 rows.

Thanks,
Saurabh.


P.S - i recently changed ft_min_word_len=2, i love how things have improved. Should i beware of any of its disadvantages?
