Stretcher - readme example

stretcher_search.rb

require 'stretcher'

# First Create a server
server = Stretcher::Server.new('http://localhost:9200')
# Delete an index (in case you already have this one)
server.index(:foo).delete rescue nil
# Create an index
server.index(:foo).create(mappings: {tweet: {properties: {text: 'string'}}})

# and here I get following exception:
# /Users/marek/.rvm/gems/ruby-1.9.3-p194/gems/stretcher-1.2.0/lib/stretcher/server.rb:136:in `request': Error processing request (400)! put URL: http://localhost:9200/foo/ (Stretcher::RequestError)
# Resp Body: #<Hashie::Mash error="MapperParsingException[mapping [tweet]]; nested: ClassCastException[java.lang.String cannot be cast to java.util.Map]; " status=400>
#  from /Users/marek/.rvm/gems/ruby-1.9.3-p194/gems/stretcher-1.2.0/lib/stretcher/index.rb:41:in `create'
#	from stretcher_search.rb:8:in `<main>'

# Add a document
server.index(:foo).type(:tweet).put(123, {text: 'Hello'})
# Retrieve a document
server.index(:foo).type(:tweet).get(123)
# Perform a search (Returns a Stretcher::SearchResults instance)
res = server.index(:foo).search({size: 12}, {query: {match_all: {}}})
res.class   # Stretcher::SearchResults
res.total   # => 1
res.facets  # => nil
res.results # => [#<Hashie::Mash _id="123" text="Hello">]
res.raw     # => #<Hashie::Mash ...> Raw JSON from the search

Ah, that is a typo, should have been: server.index(:foo).create(mappings: {tweet: {properties: {text: {type: 'string'}}}})

I'll update the README soon.
