Ruby in a nutshell

[ngoc]

I bought a "Ruby in a nutshell" book, but It does not sort after
alphabetical order at library part. Time consuming to search around it.
Any other way to search?

Have a look at http://www.ruby-doc.org/docs/rdoc/1.9/ or try using "ri"
(It usually comes with Ruby) as in "ri Object" or "ri +" or "ri Array#+".
