wget http://www.mindpin.com/static_files/tmp/solr-server.tar.gz
解压后放到任意目录后
把 solr-server/bin 目录加入 path
如果运行 solr-server 命令成功，说明配置正确

启动 solr-server

$ cd eshare
$ ./deploy/sh/solr_server.sh start

创建索引

solr服务器第一次运行起来后请在工程目录运行

$ rake sunspot:reindex

搜索基础用法

search = Course.search {fulltext params[:query]}

results = search.results # => 含有30个结果的数组

search.total           # => 搜索结果的总数60

results.total_pages    # => 2
results.first_page?    # => true
results.last_page?     # => false
results.previous_page  # => nil
results.next_page      # => 2
results.out_of_bounds? # => false
results.offset         # => 0

搜索结果配置

search = Course.search do
  fulltext params[:query] do
    boost_fields :name => 2.0 #权重
  end
  paginate :page => 2, :per_page => 15 #分页
  with :creator_id, 1 #限制结果, 第二个参数也可是数组
  facet :creator_id #分片
end

#搜索结果的分片过滤
search.facet(:creator_id).rows.each do |facet|
  puts "用户#{facet.value}创建了#{facet.count}个课程。"
end
