I am trying to map multiple analyzers to a field in my elastic type. If I use an ElasticAttribute to map an analyzer:
[ElasticProperty(Analyzer = "fulltext")]
public string LongDescription { get; set; }
and I look at the request created I get:
"name": {
"type": "string",
"analyzer": "fulltext"
},
In order to map multiple analyzers to the same field, I use Fluent mapping and add a multifield:
.Properties(prop => prop
.MultiField(mf => mf
.Name(p => p.Name)
.Fields(f => f
.String(
s =>
s.Name(n => n.Name)
.IndexAnalyzer("autocomplete_analyzer")
.IncludeInAll(false)
.Index(FieldIndexOption.not_analyzed))
.String(
s =>
s.Name(n => n.Name)
.IndexAnalyzer("fulltext")
.IncludeInAll(false)
.Index(FieldIndexOption.not_analyzed))
)
)
)
The request generated looks like this:
"name": {
"type": "multi_field",
"fields": {
"name": {
"type": "string",
"index": "not_analyzed",
"index_analyzer": "autocomplete_analyzer",
"include_in_all": false
},
"name": {
"type": "string",
"index": "not_analyzed",
"index_analyzer": "fulltext",
"include_in_all": false
}
}
},
I am specifically interested in the "analyzer"/"index_analyzer" properties. With fluent mapping, I can only set IndexAnalyzer or SearchAnalyzer. I understand the difference between IndexAnalyzer and SearchAnalyzer, but what is the "analyzer" property when I use an ElasticAttribute? Does that just mean the Index and Search are set the same?
