-* Elasticsearch
-
-** Introduction
-
-GeneNetwork uses elasticsearch (ES) for all things considered
-'state'. One example is user collections, another is user management.
-
-** Example
-
-To get the right environment, first you can get a python REPL with something like
-
-: env GN2_PROFILE=~/opt/gn-latest ./bin/genenetwork2 ../etc/default_settings.py -cli python
-
-(make sure to use the correct GN2_PROFILE!)
-
-Next try
-
-#+BEGIN_SRC python
-
-from elasticsearch import Elasticsearch, TransportError
-
-es = Elasticsearch([{ "host": 'localhost', "port": '9200' }])
-
-# Dump all data
-
-es.search("*")
-
-# To fetch an E-mail record from the users index
-
-record = es.search(
- index = 'users', doc_type = 'local', body = {
- "query": { "match": { "email_address": "myname@email.com" } }
- })
-
-# It is also possible to do wild card matching
-
-q = { "query": { "wildcard" : { "full_name" : "pjot*" } }}
-es.search(index = 'users', doc_type = 'local', body = q)
-
-# To get elements from that record:
-
-record['hits']['hits'][0][u'_source']['full_name']
-u'Pjotr'
-
-record['hits']['hits'][0][u'_source']['email_address']
-u"myname@email.com"
-
-#+END_SRC
-
-** Health
-
-ES provides support for checking its health:
-
-: curl -XGET http://localhost:9200/_cluster/health?pretty=true
-
-#+BEGIN_SRC json
-
-
- {
- "cluster_name" : "asgard",
- "status" : "yellow",
- "timed_out" : false,
- "number_of_nodes" : 1,
- "number_of_data_nodes" : 1,

- "active_shards" : 5,
- "relocating_shards" : 0,
- "initializing_shards" : 0,
- "unassigned_shards" : 5
- }
-
-#+END_SRC
-
-Yellow means just one instance is running (no worries).
-
-To get full cluster info
-
-: curl -XGET "localhost:9200/_cluster/stats?human&pretty"
-
