series index doesn't get all digits

[Thorsten90]

Hello,

I want to add several files to Calibre. The files are named series_-_title_seriesindex.ext or series_-_seriesindex.ext. Series and title may contain numbers. I can't add those files seperatly, and changing the filenames isn't an option.

This is the expression i wanted to use:

(?P<series>[^_]*)-(?P<title>[^_.]*)(?P<series_index>\d+.*)

My problem is, that it doesn't get the whole series index, only two digits. For example, if the index in a filename is 123.4 (some indices are decimal numbers) i get 3.4 as index, the rest is added to the title. If the index is 123 i get 23. The numbers don't have the same number of digits.

Any advice would be appreciated.
