Subject Re: How to index and search (integer or float) vector.
Date Fri, 13 Apr 2018 14:32:15 GMT
I think that perhaps something along PointType or
IntPointField/FloatPointField would be the right answer to store

On the other hand, I am not sure what "searching similar vectors" mean
for you, I suspect there are different meanings. It may be something
like using a dist function:

Or it may be a custom similarity.

The other two avenues may be Learning-to-rank:
Or streaming expressions
(the documentation is lagging a bit, as individual evaluators are
developed very quickly....)

I haven't seen any examples in the wild using the above, which is why
I am a bit hesitant. So, I suspect some further digging would be
needed. And I have a feeling that each of the approaches above are not
cross-linked, so you really need to be clear on what those vectors are
for you and what 'search' means.

P.s. If you do get it to work, a follow-up summary email would be
fantastic resources for others searching this kind of information
