Correcly search for book's title with double quote (").

At indexation time, double quote are ignored, so a title as
`TED "talks" - Business` is indexed as `ted talks business`.

By removing the quotes, we ensure that our title "phrase" is not closed
too early and we correctly search for `ted PHRASE talks PHRASE business`
instead of `ted AND talks AND business`.
