As we said in the beginning of this chapter, we treat the book you are holding in your hands as a continuation of the Elasticsearch Server Second Edition book. Because of this, we would like to continue the story that we've used in that book. In general, we assume that we are implementing and running an online book store, as simple as that.
The mappings for our library index look like the following:
{
"book" : {
"_index" : {
"enabled" : true
},
"_id" : {
"index": "not_analyzed",
"store" : "yes"
},
"properties" : {
"author" : {
"type" : "string"
},
"characters" : {
"type" : "string"
},
"copies" : {
"type" : "long",
"ignore_malformed" : false
},
"otitle" : {
"type" : "string"
},
"tags" : {
"type" : "string",
"index" : "not_analyzed"
},
"title" : {
"type" : "string"
},
"year" : {
"type" : "long",
"ignore_malformed" : false
},
"available" : {
"type" : "boolean"
},
"review" : {
"type" : "nested",
"properties" : {
"nickname" : {
"type" : "string"
},
"text" : {
"type" : "string"
},
"stars" : {
"type" : "integer"
}
}
}
}
}
}The mappings can be found in the library.json file provided with the book.
The data that we will use is provided with the book in the books.json file. The example documents from that file look like the following:

Downloading the example code
You can download the example code files for all Packt books you have purchased from your account at http://www.packtpub.com. If you purchased this book elsewhere, you can visit http://www.packtpub.com/support and register to have the files e-mailed directly to you.
To create the index using the provided mappings and to index the data, we would run the following commands:
curl -XPOST 'localhost:9200/library' curl -XPUT 'localhost:9200/library/book/_mapping' -d @library.json curl -s -XPOST 'localhost:9200/_bulk' --data-binary @books.json
