Elasticsearch queries failing #116
Description
Hello,
For some reason the queries made by Graph Explorer to the Elasticsearch seem to fail. I have tried installing GE both from PyPI with pip and from latest source using git, both result in the same problem.
For example, when making a query "list" in the GE web ui, GE returns: "Targets matching 0/229 (limit 500), Graphs matching 0/0" on the web ui, and the following is logged by GE:
2014-05-27 03:48:29,234 - app - DEBUG - making sure index exists..

If I make that same logged query manually to ES, I get zero hits:
curl -XGET 'http://127.0.0.1:9200/graphite_metrics2/_search?pretty=1' -d '{"query" : {"filtered": {"filter": {"and": [{"prefix": {"tags": "target_type="}}, {"prefix": {"tags": "unit="}}]}, "query": {"match_all": {}}}}}'
{
"took" : 8,
"timed_out" : false,
"_shards" : {
"total" : 5,
"successful" : 5,
"failed" : 0
},
"hits" : {
"total" : 0,
"max_score" : null,
"hits" : [ ]
}
}
I noticed that if I leave the "=" characters away from the query (from "target_type=" and "unit=", then I do get some real hits from ES;
curl -XGET 'http://127.0.0.1:9200/graphite_metrics2/_search?pretty=1' -d '{"query" : {"filtered": {"filter": {"and": [{"prefix": {"tags": "target_type"}}, {"prefix": {"tags": "unit"}}]}, "query": {
"match_all": {}}}}}'
