Ich habe Rails 4 Beta1-Anwendung mit mehreren Motoren. Ich habe sunspot_rails gem /2.0.0.pre.130115/ in meiner Host-Anwendung installiert. Die meisten meiner Modelle lebten in engine1. Ich habe sie für andere Motoren verwendet. Nachdem ich sunspot_rails installiert habe, benutze ichrake sunspot:solr:run ich habecommand/task not found. Laut Dokumentation habe ich eine Lösung gefunden. Hier ist der Link:https://github.com/sunspot/sunspot/wiki/Adding-Sunspot-search-to-Rails-in-5-minutes-or-less

Nachdem ich einen neuen Datensatz erstellt habe, hat Solr ihn bei einer Suche gefunden. Aber als ich meine Daten neu indizierte, wurden alte Datensätze durch eine Suche immer noch nicht gefunden. Meiner Meinung nach hat reindex nicht funktioniert. Ich habe versucht, solr server zu stoppen und neu zu starten, habe meinen PC einige Male neu gestartet, aber kein Glück. Irgendeine Idee?

Manuell erzeugte Solr-Aufgabe:

namespace :sunspot do
  namespace :solr do
    desc 'Start the Solr instance'
    task :start => :environment do
      case RUBY_PLATFORM
      when /w(in)?32$/, /java$/
        abort("This command is not supported on #{RUBY_PLATFORM}. " +
              "Use rake sunspot:solr:run to run Solr in the foreground.")
      end

      if defined?(Sunspot::Rails::Server)
        Sunspot::Rails::Server.new.start
      else
        Sunspot::Solr::Server.new.start
      end

      puts "Successfully started Solr ..."
    end

    desc 'Run the Solr instance in the foreground'
    task :run => :environment do
      if defined?(Sunspot::Rails::Server)
        Sunspot::Rails::Server.new.run
      else
        Sunspot::Solr::Server.new.run
      end
    end

    desc 'Stop the Solr instance'
    task :stop => :environment do
      case RUBY_PLATFORM
      when /w(in)?32$/, /java$/
        abort("This command is not supported on #{RUBY_PLATFORM}. " +
              "Use rake sunspot:solr:run to run Solr in the foreground.")
      end

      if defined?(Sunspot::Rails::Server)
        Sunspot::Rails::Server.new.stop
      else
        Sunspot::Solr::Server.new.stop
      end

      puts "Successfully stopped Solr ..."
    end

    # for backwards compatibility
    task :reindex => :"sunspot:reindex"
  end
end

Mein Modell:

# encoding: utf-8

class Product < ActiveRecord::Base

  ##
  # Sunspot
  searchable auto_index: true, auto_remove: true do
    text :name, boost: 5
    text :description, boost: 4
    # integer :store_id
  end
end

Und schließlich die schema.xml von solr

 This is the Solr schema file. This file should be named "schema.xml" and
 should be in the conf directory under the solr home
 (i.e. ./solr/conf/schema.xml by default) 
 or located where the classloader for the Solr webapp can find it.

 This example schema is the recommended starting point for users.
 It should be kept correct and concise, usable out-of-the-box.

 http://wiki.apache.org/solr/SchemaXml

 PERFORMANCE NOTE: this schema includes many optional features and should not
 be used for benchmarking.  To improve performance one could
  - set stored="false" for all fields possible (esp large fields) when you
    only need to search on the field but don't need to return the original
    value.
  - set indexed="false" if you don't need to search on the field, but only
    return the field as a result of searching on other indexed fields.
  - remove all unneeded copyField statements
  - for best index size and searching performance, set "index" to false
    for all general text fields, use copyField to copy them to the
    catchall "text" field, and use that for searching.
  - For maximum indexing performance, use the StreamingUpdateSolrServer
    java client.
  - Remember to run the JVM in server mode, and use a higher logging level
    that avoids logging every request
