# Range Filter on array with different range

Hi all.

I have an index named 2000 on my Elasticsearch cluster, here is the map:

``````curl -XGET "192.168.1.140:9200/2000/_mapping?pretty"
{
"2000" : {
"mappings" : {
"testData" : {
"properties" : {
"faceFeature" : {
"type" : "float"
}
}
}
}
}
}
``````

The content of `faceFeature` is a 128-dimensional array of `float` type. For example, it can be:

``````[0.3, 0.7, -0.4, -0.6, ...]
``````

Now I have a standard array. To make it easy, I call this array `a`. For example, `a` is:

``````[0.2, 0.8, -0.7, -0.3, ...]
``````

Now in every dimension, I hope that I can get the array in given range:

[ $0.2\pm0.5$, $0.8\pm0.5$, $-0.7\pm0.5$, $-0.3\pm0.5$, ...]

That means array like`[0.3, 0.5, -0.5, -0.6, ...]` is what I want to get but array like `[0.1, -0.1, 0.2, -0.5, ...]` is not what I want to get because its second dimension is out of the range $0.8\pm0.5$ as well as the third dimension is out of the range $-0.7\pm0.5$.

How can I do this using query?
