Hello, world

Create a property mapping using the new type attachment:

POST /trying-out-mapper-attachments
{
  "mappings": {
    "person": {
      "properties": {
        "cv": { "type": "attachment" }
}}}}

Index a new document populated with a base64-encoded attachment:

POST /trying-out-mapper-attachments/person/1
{
  "cv": "e1xydGYxXGFuc2kNCkxvcmVtIGlwc3VtIGRvbG9yIHNpdCBhbWV0DQpccGFyIH0="
}

Search for the document using words in the attachment:

POST /trying-out-mapper-attachments/person/_search
{
  "query": {
    "query_string": {
      "query": "ipsum"
}}}

If you get a hit for your indexed document, the plugin should be installed and working.
