I've got an app with 4 different models which are multisearchable, however they were originally set up with a pg_search_scope; ie:

class Episode < ActiveRecord::Base
  include PgSearch
  # multisearchable :against => [:title, :description]

  pg_search_scope :search_text,
    :against => [:title, :description],
    :using => {
               :tsearch => {:prefix => true}
              }

As you can see at one point I tried setting this up the multiserachable way.

Of late there are items we know should be returning that are NOT in the search results, and I thought I'd have to rebuild the pg_search_documents; however that's throwing an error:

irb(main):004:0> PgSearch::Multisearch.rebuild(Show)

I thought that it might be because of the setup as a pg_search_scope, so I set one class as above with the multisearch:multisearchable :against => [:title, :description] -- but even then I get rebuild problems.

I tried the manual way of deleting from the pg_search table and rebuilding but even THAT's throwing an error:

我在尝试通过 Rails 命令行使用PgSearch::Multisearch.rebuild(Professor). 对我有用的是使用Github 上推荐的替代方法从命令行重建：

rake pg_search:multisearch:rebuild[Professor]

这似乎对我有用——它不会引发错误，当我进入 Rails 控制台并运行PgSearch.multisearch("query")它时，它会返回结果，而在它返回错误之前。

我知道这不是解决办法，但它是解决眼前问题的办法。我希望它有所帮助——在他们的 Github 上发布问题可能会导致更全面的修复。
