If you're willing to assume there aren't other HP titles you'll ever want. That would also catch 'Maximizing HP', for example. (Hit points or horse power--take your pick.)

 category=>^.*Rowling.*$=>Harry Potter

Again, with the caveat that not all Rowlings are JK. Just most.

 category=>^.*Hobbit.*(Tolkien|Book|Novel).*$=>The Hobbit(Book)
 category=>^.*Lord of the Rings.*(Tolkien|Book|Novel).*$=>Lord of the Rings(Book)
 category=>^.*Hobbit.*$=>The Hobbit(Movie)
 category=>^.*Lord of the Rings.*$=>Lord of the Rings(Movie)

That particular sequence isn't going to do what you want because category=>^.*Hobbit.*$=>The Hobbit(Movie) will also apply to the The Hobbit(Book) you just changed to above it. Ditto for movie.

The best way to find out what regex will do is try them. And FanFicFare will help you out there. In personal.ini you can define test stories and give them whatever metadata you want to try out:

[teststory:1003]
title:Some Other Title
category_list:Thor (Movies),Marvel Cinematic Universe,The Avengers (Marvel Movies),Captain America (Movies),xyz,Harry Potter,a little bit fluff,angst and fluff,Hurt/Comfort,Percy Jackson and the Olympians & Related Fandoms - All Media Types
characters_list:Fred Weasley,George,Frigga (mom),Wesley W.P.,Wesley WaP.
genre_list:Action,Romance
chaptertitles:Prologue,Chapter 1\, Xenos on Cinnabar,Chapter 2\, Sinmay on Kintikin,3. Chapter 3,Chapter 4,Chapter 5,Chapter 6,Chapter 7,Chapter 8
ships_list:Thor/Jane,Bob
rating:G

Then add/update-always/update-calibre with story url test1.com?sid=1003. Just make sure the replace_metadata you're trying to test are in [defaults] or [test1.com].
