I am going to create a search engine with PHP/MySql

Now, I know how I can do exact matched, but can someone introduce me to *non exact* matches? for instance, would it be possible to sort results for $query by how many letters there are in order that are the same as the $query

for example

$query = apple
results:
1. apple
2. applepie
4. application
5. please

etc ?

What most of the big search engines do is use some kind of dictionary technique to strip the word back to it's stem. So for example, type in running reduces back to run which will then match 'Charity Fun Run'.
