title: Elasticsearch insensitive search accents
body: <p>I'm using Elastic search with Python. I can't find a way to make insensitive search with accents.</p>
  
  <p>For example:
  I have two words. "<strong>Camión</strong>" and "<strong>Camion</strong>".
  When a user search for "camion" I'd like the two results show up.</p>
  
  <p>Creating index:</p>
  
  <pre><code>es = Elasticsearch([{u'host': u'127.0.0.1', u'port': b'9200'}])
  
  es.indices.create(index='name', ignore=400)
  
  es.index(
      index="name",
      doc_type="producto",
      id=p.pk,
      body={
          'title': p.titulo,
          'slug': p.slug,
          'summary': p.summary,
          'description': p.description,
          'image': foto,
          'price': p.price,
          'wholesale_price': p.wholesale_price,
          'reference': p.reference,
          'ean13': p.ean13,
          'rating': p.rating,
          'quantity': p.quantity,
          'discount': p.discount,
          'sales': p.sales,
          'active': p.active,
          'encilleria': p.encilleria,
          'brand': marca,
          'brand_title': marca_titulo,
          'sellos': sellos_str,
          'certificados': certificados_str,
          'attr_naturales': attr_naturales_str,
          'soluciones': soluciones_str,
          'categories': categories_str,
          'delivery': p.delivery,
          'stock': p.stock,
          'consejos': p.consejos,
          'ingredientes': p.ingredientes,
          'es_pack': p.es_pack,
          'temp': p.temp,
          'relevancia': p.relevancia,
          'descontinuado': p.descontinuado,

  <p>Search:</p>
  
  <pre><code>    from elasticsearch import Elasticsearch
      es = Elasticsearch([{'host': '127.0.0.1', 'port': '9200'}])
  
      resul = es.search(
          index="name",
          body={
              "query": {
                  "query_string": {
                      "query": "(title:" + search + " OR description:" + search + " OR summary:" + search + ") AND (active:true)",
                      "analyze_wildcard": False
                  }

  <p>I've searched on Google, Stackoverflow and elastic.co but I didn't find anything that works. </p>
