Installation¶

Download Elastic and install in folder elasticsearch (no version number) inside the repository.

The local dev server on http://localhost:9200 can then be started with:

./server.sh

For indexing template in conf/template.json is used for mapping and has to be activated/loaded before first data indexing:

curl -XPUT localhost:9200/_template/template_1 -d '@conf/template.json'

The current mapping for the index can be seen with:

curl -XGET 'http://localhost:9200/openfarmsubsidies/_mapping/payment?pretty'

Deleting the current template:

curl -XDELETE localhost:9200/_template/template_1

See installed templates:

curl -XGET localhost:9200/_template/

curl 'localhost:9200/_cat/indices?v'

Delete index:

curl -XDELETE 'localhost:9200/openfarmsubsidies?pretty'

Input files have to be formatted as JSON Lines format and are prepared with the following command for indexing:

./jl2elastic inputfile.json

Index data:

curl -XPUT 'localhost:9200/openfarmsubsidies/payment/_bulk?pretty' --data-binary "@data_elastic.json"
