Hi,
We have arrays that contain a flag next to the value, e.g. to store the
availability of each book format (we need to store the raw data in this
particular format):
{
"format" : [
{ "name" : "paperback" , "available": true} ,
{ "name" : "hardcover" , "available": false}
]
}
We would like to create facets "Available format" (which would contain only
"paperback") and "Unavailable format" (which would only contain
"hardcover").
What's the best approach to create these facets in ElasticSearch? For
example: Could we define in the mapping that only format names should be
included in the index "available_formats" if the flag "available" is true
for this particular format? Or do we need to split this out already before
entering the data into ElasticSearch?
Many thanks!
Ron
