I want to choose the best one for my needs and that's why I am asking your opinion. 我想根据自己的需要选择最佳的，这就是为什么我要问您的意见。 Thanks in advance ! 提前致谢！

2 个解决方案

Make sure to separate how you want data displayed (your first two requirements) from how you want it indexed (third) from how you want to deploy. 确保将数据的显示方式（前两个需求）与索引的编制方式（第三个需求）与部署方式分开。

Let's start backwards. 让我们开始倒退。 Heroku provides limited support for machine configuration; Heroku对机器配置提供有限的支持； both options you mention require installation of a service that reads and writes files. 您提到的两个选项都需要安装读取和写入文件的服务。 Heroku has such an option in two ways: 1) PostgreSQL has a built-in full-text search capability, and 2) Heroku has made Flying Sphinx an option, as well as these other options documented on the Heroku site . Heroku通过两种方式提供了这样的选项：1）PostgreSQL具有内置的全文本搜索功能，以及2）Heroku使Flying Sphinx成为了一个选项，以及Heroku网站上记录的这些其他选项。 The first two options may provide the easiest linkage to your database, but I haven't tried other options, so it's possible they do too. 前两个选项可能提供与数据库的最简单链接，但是我没有尝试其他选项，因此它们也可能这样做。 So now you have a search index, deployed. 因此，现在您已经部署了搜索索引。

Real-time "incremental" search is purely a matter of presentation ... and maybe performance. 实时“增量”搜索纯粹是表示问题，甚至可能是性能问题。 Start typing and you start getting results is nothing more than sending requests via AJAX to the search server, typically after a short delay in typing (maybe 50ms), and handling the display of results. 开始打字并开始获取结果无非就是通过AJAX将请求发送到搜索服务器，通常是在短暂的打字延迟（可能是50毫秒）之后，然后处理结果的显示。 There are a couple of ways to make that simple written up here in this SO answer . 有几种方法可以使这个SO答案中的内容变得如此简单。

I ended up keeping the PostgreSQL engine for now but used select2 as the jquery for the presentation and was able to get a facebook like search box : 我现在暂时保留了PostgreSQL引擎，但是使用select2作为演示文稿的jquery，并且能够获得一个类似于搜索框的facebook：

Select2 with Rails and JSON Select2与Rails和JSON
