If case sensitive search does not work (calibre 2.27) then how can we search for e.g. authors in lowercase?
I need to do this because I have a few imported books that have the title and author swapped and this is a very easy way of finding them.
I've tried ^[a-z] or even ^m as a test and it returns all authors or, respectivelly or authors starting with M.

Edit:
Unfortunatelly, the solution posted by silentgy does not appear to work either.

{author:switch(^[a-z], az, )} by which I was trying to identify lowercase authors fills the column for all books with "az" even for the authors who's names start with [A-Z]

also confirmed here:
http://manual.calibre-ebook.com/template_lang.html
Many functions use regular expressions. In all cases, regular expression matching is case-insensitive.

edit2: ok there are a few functions that can work for what I'm trying; I will also test with re()

edit3: there is another problem with re() - the manual give two versions of the syntax (with 2 or 3 arguments) and only the 2 version is correct

Here (http://manual.calibre-ebook.com/temp...rn-replacement) the syntax is described as:
re(val, pattern, replacement) – return the field after applying the regular expression. All instances of pattern are replaced with replacement. As in all of calibre, these are python-compatible regular expressions

but here (http://manual.calibre-ebook.com/template_lang.html)
is:
re(pattern, replacement) – return the field after applying the regular expression. All instances of pattern are replaced with replacement. As in all of calibre, these are python-compatible regular expressions.

I know I have an auther named e.g. "time" (with no quotes).
first version (with three arguments) outputs a template error (incorrect number of arguments)
i've tried with {author:re(^t, t, zzz)} and with {author:re(^[a-z], az, zzz)}
second version {author:re(^t, t)} just copies all the authors in the custom column
(because it replaces T or t with T or t)
while {author:re(^[a-z], az, zzz)} replaces any first character with az but it is not case sensitive

so... no case sensitive search by no means?
