Hello,
We are working on a project that will use Elastic Search for search.
We do not have previous experience with it, but verry little using Solr.
I have some problems with Geo Localization for search, with which i never
had any contact in the past.
I will try to put thinks simple so i can ask specific questions:
## Current situation:
1. Data structure of a document, indexed into ES:
{
...........................
"location" : {
"type" : "point",
"coordinates" : [-67.97224, -38.94410]
},
"Latitude" : "-38.94410",
"Longitude" : "-67.97224",
.............................
}'
1. ES mappings for Geo Localization
........................
"location" : {
"type": "geo\_shape",
"tree": "geohash",
"precision": "1m"
}
.............................
2. Query that i try to use to find all documents within a rectangle defined
by coordinates; something like this is what we think we need to search
nearby documents, geographically near other documents:
curl -XPOST "[http://10.0.30.99:9200/\_search?pretty](http://10.0.30.99:9200/_search?pretty)"[http://10.0.30.99:9200/\_search?pretty](http://10.0.30.99:9200/_search?pretty)-d'
{
"query":{
"filtered": {
"query": {
"match\_all": {}
},
"filter": {
"geo\_shape": {
"location": {
"shape": {
"type": "envelope",
"coordinates" : [[-59.0, -35.0], [-58.0, -34.0]]
}
}
}
}
}
}
}'
And i get an error from ES:
..................................
nested: InvalidShapeException[maxY must be \>= minY: -34.0 to -35.0]
.......................................
1. Questions
a. At error from point 3, from what i understand ES complains that -34.0
must be greater or equal to -35, which is the case (they are negative
numbers), so why does ES complain ? Is this query ok ?
b. Is the approach used to find documents which are geographically near
other documents, that we used ok, and what fixes, improvements,
alternatives do you suggest ?
c. Could you recommend a good reference documentation/help/tutorial for GEO
localization (but not only) in ES ?
Thank you !
