Tag browser searching

Stampercam · 06-24-2011, 11:42 PM

The recent change to allow clicking on a category in the tag broswer is a great new option, however it doesn't seem to be working quite right for me.

When I go into authors and click on I it, in the tag browser it shows me the authers whose surname starts with I, but in the book list it shows the authors whose FIRST name starts with I, so instead of Greg Isle books, I'm getting Isaac Asimov etc.

Hmm, maybe it should be searching author_sort not authors, chaley will have to comment.

This got complicated. Two problems:

1) must check each author in the author_sort, but that means a complicated regexp that checks for ampersands. Didn't need to do this for authors.
2) must build a character class to handle letter equivalences in some languages.

For an example or the second problem, in some locales the letters S and Š are to sort as equivalent letters. The search must find either letter whether it is a first or later author (later authors are identified by the & character). The regex that calibre now generates to do that is

Code:

author_sort:"~(^[ŠS])|(&\\s*[ŠS])"

Code changes submitted.
