Hi,
I have a quick question about property mapping. I have an intention to
introduce a double property to an index (with default settings) and index
and search it. Here is the simple mapping that I use:
{
"myType" : {
"properties" : {
"value" : {"type" : "double"}
}
}
}
When I use java node client to index data, I can insert an java
integer value to the index, and when I search, I get it as integer
also. Naturally I can't cast it to double. Is this what should I
expect from elastic search, does the responsibility belong who uses ES
clients, or should java search give me double values ?
Thanks in advance,
Sezgin Kucukkaraaslan

What do you use to get it back from search? Do you get the source as map?

In this case, it might happen, you should just treat it as Number and call
xxxValue on it.
