Multifield: MapperParsingException when using dot

[tomasfalt]

When I map a Multifield called Name I get the following error:

MapperParsingException[Field name [name.raw] which is a multi field of [name] cannot contain '.']

I know that field name with dots is not longer allowed in ES 2.0 but I can't see a solution to this then using Multifields.

@tomasfalt Can you provide the relevant mapping please? In addition, what version of NEST and Elasticsearch are you using?

[tomasfalt]

@russcam I'm using NEST 2.0.0-alpha1 and ES 2.1.1.

The mapping:

var mapping = propertiesDescriptor.String(
                    s1 =>
                        s1.Name(p => p.Name)
                            .Analyzer("standard")
                            .Fields(fs => fs.String(s2 => s2.Name(p2 => p2.Name.Suffix("raw")).Index(FieldIndexOption.NotAnalyzed))))

I found this: https://discuss.elastic.co/t/elasticsearch-2-mapping/34366. It sounds like the same problem?

Sorry... Wrong button

@tomasfalt yea, that's correct. You don't need to supply the suffix explicitly anymore, since it's a multi-field, ES will create this for you automatically.

Just try:

 .Fields(fs => fs.String(s2 => s2.Name(p2 => p2.Name("raw").Index(FieldIndexOption.NotAnalyzed))))

@tomasfalt while my above comment will fix the issue, after some internal discussion we should change PropertyName to always resolve to the last token. I've opened #1708 for this.

Ok, great. Thanks!
