【问题标题】：Using sunspot gem and solr for indexing search results使用 sunspot gem 和 solr 索引搜索结果
【发布时间】：2014-02-25 12:01:14
【问题描述】：

使用 rails 3.0.6 ，ruby 1.9.3

Gemfile（根据需要粘贴）

gem 'rails', '3.0.6',

gem '耙子'，'0.9.2'

gem 'sunspot_rails'

宝石'sunspot_solr'

gem 'progress_bar'

我已经在 user.rb 中设置了这样的模型

Sunspot.setup(User) do
  text :resume_body, :stored => true
  text :job_title, :stored => true
 end

然后我用过

class CandidatesController < ApplicationController

  def index
    @search = Sunspot.search(User) do
      # Full text on resume body and job title with highlighting
      keywords params[:q] do
        highlight :resume_body, :max_snippets => 3, :fragment_size => 120, :merge_contiguous_fragments => true
      end

每当我运行 rake 任务时，例如 bundle exec rake 太阳黑子:solr:reindex 耙太阳黑子：重新索引

报错

错误

注意 - 该应用之前使用 sunspot 1.1，我已将其升级到 2.1

这是我第一次在开发中尝试 solr 和 sunspot，我也遵循了所有教程以确保安装正确。但是，我可能还是错过了一些东西。非常感谢任何帮助将新手指向正确方向的帮助。在此先感谢，我也非常打算在生产中使用 sunspot :)

【问题讨论】：

当太阳黑子给我废话时我总是检查的事情清单：我rake sunspot:solr:start。我bundle install。我rails generate sunspot_rails install.此外，您是否有理由在用户模型上使用 Sunspot.setup 而不是 searchable 块？这不是造成这种情况的原因，我只是好奇。
另外，请确保您对此进行了很好的测试。 Sunspot 2.1.0 将打包的 SOLR 版本从 3.5 更改为 4.2...
我确实尝试了可搜索块，因为这是一个曾经使用太阳黑子 1.1 但没有运气的旧应用程序，你提到的命令也成功触发，我也得到了结果，但搜索不到索引。
我正在使用带有太阳黑子 2.1 的 solr 4.6。
还想问，新的黑子宝石只索引文本搜索？特定用户的经纬度搜索呢？

【解决方案1】：

这可能会帮助你搭车.....

太阳黑子快速入门的步骤：

将此 gem 添加到您的 gemfile 中
```
gem 'sunspot_rails'
```
安装这个 gem 使用
```
bundle install
```
使用此命令启动 solr
```
rake sunspot:solr:start
```
举个简单的例子，考虑一个带有标题字段和内容字段的 Post 模型。我们会将这些字段索引为 Solr 文本字段。
```
rake sunspot:solr:reindex
```

这是对我们上面索引的 Post 类的简单搜索，从 PostsController 的 index 操作运行：

class PostsController < ApplicationController
 def index
   @search = Post.search do
     keywords params[:query]
   end
   @posts = @search.results
 end
end

现在我们可以在视图中使用@posts 变量来执行index 操作。结果会随之而来

注意：这只是理解 flow 和 get 的一个最简单的例子从太阳黑子 solr 索引和搜索开始......有很多其他应根据我们的要求使用的选项。
