Hi All,
I'm using Elasticsearch for searching by Geo Point, and I am experiencing a
very weird issue. Sometimes my search works fine, but suddenly, for no
obvious reasons it starts throwing an internal Elasticsearch error:
java.lang.NumberFormatException: empty String

I am pretty much sure that my data hasn't changed, it's valid, I can search
it using other queries and filters, so it's not my data issue. The error is
intermittent, so I cannot even make a reproducible example (I wasted a few
hours for trying doing that with no success).
I am using the MongoDB river plugin to populate the Elasticsearch index and
it makes creating a curl recreation even more difficult task.
I was able to reproduce this error having one single item in my index, but
when I create a new index with identical settings and curl that document in
it just works. When I took that item and simply re-inserted it into the
original index via curl -X PUT it started working there too. After that I
wasn't able to reproduce the error even doing complete repopulating my
database and making it replicated to Elastic via rivers.
It was gone for about 3 days and today I got it as well. Upgrading from
0.90.3 to 0.90.5 din't help.
I tried to look through the Elasticsearch source codes hoping that I could
potentially understand what could cause that error in order to at least
find proper reproducing steps, but unfortunately I had to gave up -
rummaging in elastic guts turned our to be too tough exercise to me 
Please help me to understand what can cause this error. Is it Elastic bug
or mongodb-river bug or may be it's just me being doing something stupid.
I'm stuck and it's a blocking issue to me. Thank you in advance!
Here's my setup:
A document:
{
"_id": "5238c96693f4a7ca2b1a05e0",
"version": 0,
"name": "Venue2921",
"venueType": "Some type. Don't know yet",
"location": {
"version": 0,
"point": [
20.45349323402702,
47.9058385892468
]
},
"address": "Praha 1",
"facilities": [
{

"_id": "5238c95893f4a7ca2b1943f6",

},

},
{

"names": {

}
],
"fieldIds": [
"5238c96693f4a7ca2b1a05e1",
"5238c96693f4a7ca2b1a05e9"
]
}
... and the mapping:
{
"venue": {
"_all": {
"enabled": false
},
"properties": {
"location": {
"properties": {
"name": {
"type": "string"
},
"point": {
"type": "geo_point",
"lat_lon": true
},
"timezone": {
"type": "string",
"index": "not_analyzed"
}
}
}
}
}
}
... and the query:
{
"query": {
"filtered": {
"filter": {
"geo_distance" : {
"location.point" : [ 14.5, 50.1 ],
"distance" : "20km"
}
}
}
}
}
... and finally, the result:
