rake search:node:create MODEL=User RAILS_ENV=production - for every model/environment you use
As Rails plugin(recommended <-> rake tasks/cap recipes):
script/plugin install git://github.com/grosser/search_do.git
Or as Gem:
sudo gem install searh_do
install will_paginate to use “paginate_by_fulltext_search” (Instruction: github.com/mislav/will_paginate/wikis/installation)
#MODEL
class User < ActiveRecord::Base
acts_as_searchable(
#fields the will be found in fulltext search
:searchable_fields => [:name,:website,:city,:about],
#fields used for attribute search/ordering
:attributes => {:name=>nil,:city=>nil,:country=>nil,:age=>nil}
)
attr_accessor :html_snippet #add this to get html snippets on your results (see below)
end
#SEARCH
Users who:
- contain 'hello' in any of their searchable fields
- whose website attribute contains 'www' (contains search for strings)
- whose age is 1 (exact match for numbers/dates)
- sorted by age ASC
@results = User.paginate_by_fulltext_search('hello',:attributes=>{:website=>'www',:age=>1},:order=>'age ASC',:page=>1,:per_page=>20)
(Same can be done without pagination: User.fulltext_search)
#SNIPPETS
Each record found with a fulltext-search (not a attribute-only search) contains a snippet
of the surrounding where the phrase was found.
User.fulltext_search('hello') => user.html_snippet == "id like to say <b>hello</b> to my fellow students"
NOTE: html_snippet will not contain HTML except for the <b>, so there is no need to escape it.
- Phrase search, regular expressions, attribute search, and similarity search - Snippet retrival - UTF8 support - Web interface - Built in P2P clustering of index servers
