Matrix sum of multi-valued field

[Oliver Mannion]

Hi,

If I have documents with a multi-valued field of doubles, eg:

{

 levels: [0, 0.1, 2, 2.2]

}

{

levels: [1, 1.1, 3, 4]

}

Is it possible to do a matrix sum of  the levels field, eg: summing each individual value with other values in the same position to get

sumLevels: [1, 1.2, 5, 6.2]

If not, then I will have to consider the alternative of breaking the levels multi-valued field into separate fields (however the number of values is not fixed), or documents (would work, but will be a lot more documents).

Regards,

Oliver

Yeah, I think the only way to do this currently is to use multiple fields.

level_1_d : 1
level_2_d : 1.1
level_3_d : 3
level_4_d : 4

And then ask for sum(level_1_d), etc...
