Enabling geohash indexing on Geo Point type

Elastic Stack Elasticsearch
1

Hi,

I have defined the mapping below on my index:

{
"poi" : {
"properties" : {
"location" : {
"type" : "geo_point",
"geohash" : true
},
...
}
}
}

I'm now trying to make a query where I search by geohash, but I can't
figure out which field to reference. Also, what kind of queries am I
allowed to do on the geohash?

Thanks,
Gianluca

The field you'd search is "location" and the docs on the geo shape filter
are here:

Although, beware - the docs should be updated soon. "within" and "disjoint"
are no longer supported as their implementation was buggy

Hi,

the closest example that I found in the docs is below:

{
"filtered": {
"query": {
"match_all": {}
},
"filter": {
"geo_shape": {
"location": {
"shape": {
"type": "envelope",
"coordinates":[[-45,45],[45,-45]]
},
"relation": "within"
}
}
}
}
}

What I have available client side is a geohash value, describing the cell I
want to search in. I might translate that to a pair of coordinates, but is
there a way to give the value directly in the filter?

Thanks,
Gianluca

I don't think you can combine geohashes with geo-shapes, at least not yet.

Perhaps open an issue requesting it?
