ABOUT:

ActiveLucene is an ActiveRecord/ActiveModel’s like interface to Apache Lucene, with support for dynamic attributes, pagination, highlighting and Lucene’s query syntax.

ActiveLucene was extracted from Lunr:

https://github.com/dcrec1/lunr

ActiveLucene works with JRuby like this:

class Advertise < ActiveLucene::Document
end

Advertise.create! :param1 => 'value 1', :param2 => 'value 2'

Advertise.find :all
Advertise.find "5"

Advertise.search "value*"
Advertise.search "param2:'value 2' AND param3:lorem"
Advertise.search "param2:value OR param3:lorem"

Advertise.search :param1 => 'value 1', :param2 => 'value'

Advertise.serach(:param1 => 'va?ue').first.highlight

Advertise.serach(:param1 => 'va?ue').total_pages

Advertise#search accepts as a parameter any query supported by Lucene. For more information:

Note that you don’t need to specify attributes, they are dynamic!

The pagination is supposed to be compatible with will_paginate:

For more examples, please refer to the specs.
