如何使用sunspot_rails gem 搜索相关文章

发布于 2024-11-29 16:19:52 字数 612 浏览 4 评论 0原文

我有一个迷你博客应用程序，我希望用户查看与他们在文章显示页面中阅读的内容相关的文章。做类似的事情

如果没有 sunspot_rails gem，我会在我的模型中

  def self.related_search(query, join = "AND")
    find(:all, :conditions => related_search_conditions(query, join))
  end

  def self.related_search_conditions(query, join)
    query.split(/\s+/).map do |word|
      '(' + %w[name description notes].map { |col| "#{col} LIKE #{sanitize('%' + word.to_s + '%')}" }.join(' OR ') + ')'
    end.join(" #{join} ")
  end

，然后在我看来，它会像这样，

@article.related_search

但我想使用 sunspot_rails gem 使这种方式变得简单。任何帮助。谢谢

  end

  def self.related_search_conditions(query, join)
    query.split(/\s+/).map do |word|
      '(' + %w[name description notes].map { |col| "#{col} LIKE #{sanitize('%' + word.to_s + '%')}" }.join(' OR ') + ')'
    end.join(" #{join} ")

正如 RocketR 提到的，这是 Sunspot 的一个简单用例。

首先，使用 Sunspot 指定将三个字段作为文本索引。

class Article < ActiveRecord::Base
  searchable do
    text :name
    text :description
    text :notes
  end
end

然后可能从控制器操作中发出搜索。下面的 @search 对象包含有关搜索响应的元数据，包括其 results 方法下的匹配对象。

@search = Article.search do
  keywords query
end
@results = @search.results

要查找与已加载的对象类似的其他文档（例如在 show 操作中），您可以调用 more_like_this 实例方法。这是一种特殊的搜索，它使用 Solr 的“More Like This”功能，并返回与上面的全文搜索类似的搜索对象。您可以使用其 results 方法来呈现该搜索的结果。

<%= render @article.more_like_this.results %>

more_like_this 方法也接受具有类似的块搜索块的选项，以便您可以更好地控制如何判断相似性。

希望有帮助！

As RocketR mentions, this is a trivial use case for Sunspot.

First, use Sunspot to specify that you have three fields to be indexed as text.

class Article < ActiveRecord::Base
  searchable do
    text :name
    text :description
    text :notes
  end
end

Then issue a search, likely from within a controller action. The @search object below contains metadata about the search response, including the matching objects under its results method.

@search = Article.search do
  keywords query
end
@results = @search.results

To find other documents that are similar to an object you already have loaded, say in a show action, you can call the more_like_this instance method. This is a special kind of search, which uses Solr's "More Like This" functionality, and which returns a search object similar to the above full-text search. You can use its results method to render the results of that search.

<%= render @article.more_like_this.results %>

The more_like_this method also accepts a block with similar options to the search block, so you can have more control over how you're judging similarity.

Hope that helps!
