简单搜索仅搜索记录的最后一个单词

Question

I set up a simple search as instructed in part of railscast #240.

in controller

 @reports = Report.search(params[:search]).order('created_at DESC').paginate(:page => params[:page], :per_page => 5)

in model

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

in view

<%= form_tag reports_path, :method => :get do %>
    <p>
        <%= text_field_tag :search, params[:search] %>
        <%= submit_tag "Search", :name => nil %>
    </p>
<% end %>

it all works... but...
I have a few records for example, one with "another time test" and another with "last test of time"
if i search "test" the first comes up but the second doesn't, and if i search "time" the second comes up but not the first. It is only seeing the last word of the record.

what gives?

Answer 1

You need to put a percent sign on both sides of the search term. Like so:

where('apparatus LIKE ?', "%#{search}%")

By putting the percent sign before the search term, you're leaving everything before it as a wildcard. However, you're also saying, by not putting after the search term, that nothing after this should be considered a wildcard. That's why it only matching the last word.
