Regex Search in Advanced Search Box

franknight · 07-08-2020, 09:48 AM

He all:
I get along pretty well with Regex in calibre using it modify titles. But I'm having trouble with a regular expression search in the Advanced Search: Regular Expression: Author field. I want to search my library for authors that have initials without a '.' after the initial. The format of all such authors in my library (which is quite large) is 'capital letter' followed by '.' followed by a 'space' I want to find the ones where I forgot the '.' So 'John A. Trouble' is OK. But I want to find 'John A Trouble' Closest I've come with my meager knowledge of Regex is "X +" which finds all authors with an 'x' at the end of either their first or last name. Doesn't even restrict the finds to a capital 'X' Thanks for looking at my dilemma. frank

If I am understanding you correctly, you want to find any author containing a space then a single letter then a space. If so, then this works

Code:

author:"~ \w "

If the single letter can be the first letter of the author's name then this works:

Code:

author:"~(^| )\w "

@franknight: Try the Quality Check plugin. It has a search for authors with initials and can fix the missing dot.
