搜索句子 [英] Search through sentences

问题描述

我有一个 rails 应用程序并决定进行搜索.我有一个搜索文本字段，控制器负责一切.在我的搜索方法中

I have a rails app and have decided to have a search. I have a search textfield and the controller takes care of everything. In my search method

def self.search(search)
    if search
      str = []
      search.split.each do |s|
        a = find(:all, :conditions => ['title or content LIKE ?', "%#{s}%" ])
        str = (str + a).uniq
      end

    else
      find(:all)
    end
  end

我希望能够处理多个单词搜索.如果您删除 each...loop，它可以在 1 个单词搜索中正常工作.无论如何，我想为每个搜索到的词找到相关的帖子并返回一个组合.

I want to be able to handle multiple word searches. If you remove the each...loop it works fine with 1 word searches. Anyways, I would like to find the related posts for each word that is searched and return a combination of that.

例如.如果有人搜索最伟大的球员"，它将返回标题或内容为最伟大"的帖子的所有实例以及任何标题或内容为球员"的帖子

Ex. If someone searches "Greatest Player" it will return all instances of posts that have the title or content "Greatest" and any that have the title or content "Player"
