c# - Nest and Elastic Search - Mapping -


i trying map multiple analyzers field in elastic type. if use elasticattribute map analyzer:

[elasticproperty(analyzer = "fulltext")] public string longdescription { get; set; }

and @ request created get:

"name": {       "type": "string",       "analyzer": "fulltext"     },

in order map multiple analyzers same field, use fluent mapping , add 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 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 interested in "analyzer"/"index_analyzer" properties. fluent mapping, can set indexanalyzer or searchanalyzer. understand difference between indexanalyzer , searchanalyzer, "analyzer" property when use elasticattribute? mean index , search set same?

just specifying analyzer indeed setting index_analyzer , search_analyzer @ same time. analyzer elasticsearch property , not magic behavior nest.

the fluent mapping missing .analyzer() method, added in 1.0!
