[code lang=”bash”]curl -X PUT “192.168.0.37:9200/test” -d ‘{
“settings” : { “index” : { “number_of_shards” : 1, “number_of_replicas” : 0 }}
}’[/code]

Mapping attachement type
[code lang=”bash”]curl -X PUT “192.168.0.37:9200/test/attachment/_mapping” -d ‘{
“attachment” : {
“properties” : {
“file” : {
“type” : “attachment”,
“fields” : {
“title” : { “store” : “yes” },
“file” : { “term_vector”:”with_positions_offsets”, “store”:”yes” }
} } } } }’[/code]

Shell script to convert content to base64 encoding and index
[code lang=”bash”]#!/bin/sh</code>

coded=`cat TestPDF.pdf | perl -MMIME::Base64 -ne ‘print encode_base64($_)’`
json=”{"file":"${coded}"}”
echo “$json” > json.file
curl -X POST “192.168.0.37:9200/test/attachment/” -d @json.file
[/code]
