+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

+
+es = Elasticsearch([{ "host": 'localhost', "port": '9200' }])

+# Dump all data

+# 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" } }
