python regex first/shortest match

trying to write an regex that can find all patterns 

p = "q=http://.*\.doc" in 

text = "q=http://11111.doc,q=http://22222.doc"

when I did finall on text,

I get the whole thing, i.e. q=http://11111.doc,q=http://22222.doc

but not q=http://11111.doc and q=http://22222.doc

how do I fix it?

That's because * is a greedy quantifier, trying to match as much as it can. Make it *?:

q=http://.*?\.doc
