Get first 4 items returned from db where title matches searched criteria

gistfile1.rb

      @items += Item.where( "lower(title) ~* ?", "#{params[:s].downcase}".split(/,\s*/).map(&:strip).reject(&:empty?).first)
      @items += Item.where( "lower(title) ~* ?", "#{params[:s].downcase}".split(/,\s*/).map(&:strip).reject(&:empty?).second)
      @items += Item.where( "lower(title) ~* ?", "#{params[:s].downcase}".split(/,\s*/).map(&:strip).reject(&:empty?).third)
      @items += Item.where( "lower(title) ~* ?", "#{params[:s].downcase}".split(/,\s*/).map(&:strip).reject(&:empty?).fourth)

The first line of code here returns results that match the first search term, the second line of code returns results matching the second term... and so on. So if I enter a search query like this: "h,horse,pizza, fred," I'll get results for each of those terms returned.

Specifically, it's looking up the title attribute of my Collection object. Does that make any sense?

To answer your question regarding what's returned when I ask what class this is: 'ActiveRecord_Relation'

Everything's working with the way I wrote this code. Just wondering if there's any way to dry it up. Thanks!!!

Just thought of something dumb... I guess (at the very least) I could probs make the first half of this statement a variable and re-use that way...
