Ruby Ferret简单索引和搜索示例第1部分

Posted 2021-02-27

This is a simple example for building a search index with the Ferret library (based upon http://kasparov.skife.org/blog/src/ruby/ferret.html).

require 'rubygems'
require 'ferret'
require 'find'
include Ferret
 
index = Index::Index.new(:default_field => 'content', :path => '/tmp/index_folder')
ini = Time.now
numFiles=0
IndexedExts=['.java','.properties']
Find.find('/code/to/index') do |path|
 
 if(IndexedExts.find {|ext| path.include?(ext)}==nil)
   next  
 end 
 puts "Indexing: #{path}"
 numFiles=numFiles+1
 
 if FileTest.file? path
 	File.open(path) do |file|
 		index.add_document(:file => path, :content => file.readlines)
 	end
 end
 
end
 
elapsed = Time.now - ini
puts "Files: #{numFiles}"
puts "Elapsed time: #{elapsed} secs
"
