If you want any articles that have the word ‘linux’ in their title (it is not
an exact match), then you do not need the asterisk.
So, Article.search :conditions => {:title => ‘linux’} will match articles with
these titles:
* Linux
* Linux Experts
* Linux for Beginners
* Advanced Linux Tips
* Learning Linux
The asterisk is if you want to match parts of words - if there were titles with
linuxes, then searching with linux* would return those articles (but you also
need enable_star set to true and min_infix_len or min_prefix_len set as well):
