I tested with Python 3.5.2 (v3.5.2:4def2a2901a5, Jun 25 2016, 22:01:18) [MSC v.1900 32 bit (Intel)] on win32

re.search(r'http://v.pptv.com/show/.*?\.html.+', 'http://v.pptv.com/show/2bwkox9SS4nsatI.html?rcc_src=P5') 
does give a match, but it show the result 
<_sre.SRE_Match object; span=(0, 54), match='http://v.pptv.com/show/2bwkox9SS4nsatI.html?rcc_s>
missing rc=P5' in IDLE

BTW, py2.7 works fine

See bpo-17087: "Improve the repr for regular expression match objects".

It was decided that it might be a bad idea to show the entire matched portion of the string because it could be very long, so it's shown truncated if necessary.

[bitdancer]

If it is truncated, should it end with '...' or [...]?

[iMath]

I think so, the current behavior is misleading

Probably "...", although we also have to consider that the matched portion could in fact not be truncated but just happen to end with "...", although that would be a rare occurrence.
