Guid properties are not mapped, any reason why not?

[jakejscott]

I want to be able to exact match on a Guid. So I am using the following mapping:

[ElasticProperty(OmitNorms = true, Index = FieldIndexOption.not_analyzed)]
public Guid OrganisationId { get; set; }

But NEST omits Guid types (I think). So I have to use a string for the OrganisationId (which is an easy fix) but I couldn't work out what was going on for a while because my primary key field was also a Guid named 'Id' and that was being picked up by NEST and used as the elastic _id field.

Cheers

Just went through the exact same thing.

For .net types that do not match 1:1 with the ES type, you need to explicitly set the ES type. e.g:

[ElasticProperty(Type = FieldType.string_type, OmitNorms = true, Index = FieldIndexOption.not_analyzed)]
public Guid OrganisationId { get; set; }

But I do agree it is misleading due to public Guid Id properties working without any special mapping due to the default 'Id' property name matching.
