I have a product database, where products have a set delivery zones,
represented in elasticsearch as an array:
[
{
distance: double (in miles),
location: geohash (source location of product/seller),
deliveryprice: double
}
]
does anyone have any idea how I can filter using the distance within the
document?
I know the co-ordinates of my users, and I like to filter out products that
don't cannot be delivered to their location - in other words, where the
distance "double" field is greater than the distance between their
co-ordinates and the source co-ordinates of the product.
All the examples of goedistance filtering I've seen require the distance to
be provided in the query - not analysed from the document itself.
I'm not sure if I can use scripting to do this - if so, how?
Any help would be hugely appreciated!
Tom.
