My NEST code which used to work with Elasticsearch version 6, is throwing the following error with Elastichsearch version 7:
Failed to parse mapping [_doc]: Root mapping definition has unsupported parameters:
I have seen this question which explain mapping types are deprecated in ES 7... I am not sure if this my problem or not? How can resolve this issue?
This is my code for generating index:
var createIndexResponse = ElasticClient.CreateIndex(IndexName, c => c
.Settings(st => st
.Analysis(an => an
.Analyzers(anz => anz
.Custom("result_suggester_analyzer", rsa => rsa
.Tokenizer("standard")
.CharFilters("html_strip", "mapped_words_char_filter")
.Filters(new string[] { "english_possessive_stemmer", "lowercase", "asciifolding", "stop_words", "english_stemmer", "edge_ngram_token_filter", "unique" })
)
.Custom("custom_english_analyzer", ce => ce
.Tokenizer("standard")
.CharFilters("html_strip", "mapped_words_char_filter")
.Filters(new string[] { "english_possessive_stemmer", "lowercase", "asciifolding", "stop_words", "english_stemmer", "unique" })
)
)
.Normalizers(nor => nor
.Custom("custom_ignore_case_normalizer", icn => icn
.CharFilters("mapped_words_char_filter")
.Filters(new string[] { "lowercase", "asciifolding" })
)
)
.CharFilters(cf => cf
.Mapping("mapped_words_char_filter", md => md
.Mappings(
"C# => csharp"
)
)
)
.TokenFilters(tfd => tfd
.EdgeNGram("edge_ngram_token_filter", engd => engd
.MinGram(2)
.MaxGram(10)
)
.Stop("stop_words", sfd => sfd.StopWords(_stopWords))
.Stemmer("english_stemmer", esd => esd.Language("english"))
.Stemmer("english_possessive_stemmer", epsd => epsd.Language("possessive_english"))
)
)
)
.Mappings(m => m.Map<AdDocument>(d => d.AutoMap())));
This is MyDocument
[ElasticsearchType(Name = "ad")]
public class AdDocument
{
public long Id { get; set; }
[Text(Analyzer = "custom_english_analyzer", SearchAnalyzer = "custom_english_analyzer")]
public string FirstName { get; set; }
// searchable properties from AdBase
public bool IsActive { get; set; }
[Text(Analyzer = "custom_english_analyzer", SearchAnalyzer = "custom_english_analyzer")]
public string Title { get; set; }
public short AdDurationInDays { get; set; }
public DateTime AdStartTime { get; set; }
[Keyword(Index = false)] // Keyword => not analyzed
public string MainPhotoUrl { get; set; }
[Text(Analyzer = "custom_english_analyzer", SearchAnalyzer = "custom_english_analyzer")]
public string StoreName { get; set; }
// searchable properties from Address
public GeoLocation GeoLocation { get; set; }
[Keyword(Normalizer = "custom_ignore_case_normalizer")] // keywords => not analyzed, use ignore case normalizer otherwise search would be case sensitive
public string Suburb { get; set; }
// Price is used when something is being sold, in case of real estate rental it indicates the rent value, in case of Jobs it is not used (we use salary) and services have not price
public decimal? Price { get; set; }
public DateTime? AvailableFrom { get; set; }
public bool? IsFurnished { get; set; }
public long? LandArea { get; set; }
public short? JobTypeId { get; set; }
}
And this is the response (error) from Elasticsearch:
Failed to parse mapping [_doc]: Root mapping definition has unsupported parameters:
[ad : {
properties= {
landArea={
type=long
},
isFurnished={
type=boolean
}, isActive={

type=text
},
availableFrom={

mainPhotoUrl={
index=false,
type=keyword
},
price={
type=double
},
storeName={
search_analyzer=custom_english_analyzer,
analyzer=custom_english_analyzer,
type=text
},
id={

firstName={
search_analyzer=custom_english_analyzer,

}]
