= delsolr

http://delsolr.rubyforge.org

== DESCRIPTION:

DelSolr is a light weight ruby wrapper for solr.  It's intention is to expose the full power of solr queries 
while keeping the interface as ruby-esque as possible.

== Installation

Can be installed as a gem which is hosted on http://gemcutter.org

    gem install delsolr

or as a plugin...

    ruby script/plugin install git://github.com/avvo/delsolr.git


== PROBLEMS:

* Not threadsafe yet

== SYNOPSIS:

See http://delsolr.rubyforge.org for more info

Example:

    c = DelSolr::Client.new(:server => 'solr1', :port => 8983)

    # adding things
    doc = DelSolr::Document.new
    doc.add_field('id', 'ABC-123')
    doc.add_field('name', '8 Gig Shuffle')
    doc.add_field('description', 'A crazy-tiny MP3 player')
    c.update!(doc) # posts new document to solr
    c.commit! # posts a commit to solr

    rsp = c.query('dismax', :query => 'shuffle mp3 player')
    puts rsp.ids[0]

    # query for things
    rsp = c.query('dismax', :query => 'mp3 player',
                            :filters => {:cost => (50..100)},
                            :facets => [{:field => 'brand', :limit => 10},
                                        {:query => {:onsale => true, :brand => 'Apple'},
                                         :name => 'cheap_apple'}])

    # output total matches
    puts rsp.total

    # output each id with score
    rsp.docs.each { |doc| puts "#{doc['id']} - #{doc['score']}" }

    # output each value for a facet
    rsp.facet_field_values('brand').each do |brand|
      puts "#{brand}: #{rsp.facet_field_count('brand', brand}"
    end

    # output a query facet
    puts "Cheap Apple stuff: #{rsp.facet_query_count_by_name('cheap_apple')}"



== REQUIREMENTS:

You need Solr installed somewhere so you can query it ;)

== INSTALL:

sudo gem install delsolr

== TODO:

 * implement delete_by_query
 * make thread safe
   * it would be nice to be able to have things like commit/optimize be ran in threads on timers periodically
   * right now a few things need to be locked
     * connection
     * pending_documents array
