我在我的应用程序中添加了即时搜索功能。

它完全按照我在本地服务器上的要求工作：

  • 缩小按键列表
  • 不分大小写
  • 允许重置（因此，如果我键入内容然后将其删除，则搜索会重置，并且不会变窄）。它也允许回溯，所以如果我输入错误并删除了错误输入的字母，搜索会相应地修复。

在生产中，这种行为是完全奇怪的。虽然它也进行按键搜索，但它有许多奇怪的问题。

  • 它区分大小写（与开发不同）——这不是我想要的。
  • 关于重置，它的行为很奇怪。如果我输入“instatn”之类的内容然后更正错误，它不会重做搜索。如果我删除整个条目，它也不会重做搜索。然而，奇怪的是，
  • 如果我删除搜索词然后键入一个字母，它会重置搜索。
  • 它似乎没有正确搜索，期间。如果我输入“z”，尽管我正在搜索的所有项目都不包含“z”，但它们都不会消失。另一方面，如果我输入“Blogging”，列表实际上会缩小到名称中包含该词的两个项目。

知道这里发生了什么吗？为什么两者不同？我该如何解决？让我知道什么样的代码可能有助于解释。

我的代码：

存档.html.erb

<%= form_tag @post, :method => 'get', :id => "posts_search", class: "search_form squeeze form-inline" do %>
  <p>
    <%= text_field_tag :search, params[:search], 
    placeholder: "Search titles:", id: "search_field" %>
    <%= submit_tag "Search", name: nil, class: "btn squeeze search" %>
  </p>
  <div id="list"><%= render 'search' %></div>
<% end %>

_search.html.erb

<ul class="blog_links">
<% @posts.first(@link_num).each do |p| %>
    <li class="total_hover">
        <%= p.name %>
    </li>
<% end %>
</ul>

归档.js.erb

$("#list").html("<%= escape_javascript(render("search")) %>");

post_controller.rb

  def archive
    @posts = Post.search(params[:search]).reverse

    respond_to do |format|
      format.html # index.html.erb
      format.json { render json: @posts }
      format.js
    end
  end

 def search
    @posts = Post.search(params[:search]).reverse
    render json: { results: @posts }
 end

post.rb

  def self.search(search)
    if search
      where('name LIKE ?', "%#{search}%")
    else
      scoped
    end
  end

javascripts/posts.js.coffee

@search = ->
  $.get $('#posts_search').attr("action"), $("#posts_search").serialize(), null, "script"

$ ->
  $('#posts_search input').keypress -> search()

  $('#posts_search').submit (e) ->
    e.preventDefault()
    search()

路线.rb

match '/search', to: 'posts#search'
match '/archive', to: 'posts#archive'

编辑为了提供一些线索，我在两种环境中执行相同的用户行为并发布博客。我要做的是：

  1. 加载包含搜索的页面。
  2. 输入“Blgo”
  3. 删除“go”并将其替换为“og”
  4. 删除所有内容并搜索“Insta”

同样，虽然开发搜索工作得很好，而且我认为通常可以预期，但在生产中，上面发生的情况是：列表缩小，直到我在“blg”中输入 g，此时没有更多列表项目。当我删除“go”并输入“og”时，列表没有重新扩展以合并标题中带有“blog”的项目。当我删除搜索框中的所有字母时，它也没有包含所有内容。

搜索仅在我输入“I”时重置，并且因为 Instant 实际上是列表中的一个术语，所以它缩小到名称包含“Insta”的一个项目。

太奇怪了。有什么想法吗？

这（析取）最终只是一个数据库问题。

我正在运行 sqlite 开发和 postgresql 生产，两者对我的搜索方法的反应不同。当我将开发切换到 pg 时，搜索在两种环境中都同样失败，因此我决定使用 Thinking Sphinx 而不是自制解决方案。
