I don't see how it would scale with the number of book pages we have, neither do I understand how people would be able to find anything by title. A lot of titles start with 'A', 'The' or other stop words. It might be more useful to go with an actual keyword based index and do something like a tag cloud? Anyway, I've added this Questions for Mark Boulton and Theme TODO and style guide changes/questions.

For example:

mysql> select count(*) from node where type = 'book' and title like 'A%';
+----------+
| count(*) |
+----------+
|      348 | 
+----------+
1 row in set (0.04 sec)


mysql> select count(*) from node where type = 'book' and title like 'D%';
+----------+
| count(*) |
+----------+
|      362 | 
+----------+
