Question

我已经看到this question解释了ES 7中不推荐使用的映射类型...我不是这不是我的问题，但是以下NEST代码可用于ES6，并且出现以下错误ES7：

这是我用于生成索引的代码：

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())));

这是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; }
}

这是Elasticsearch的响应（错误）：

Failed to parse mapping [_doc]: Root mapping definition has unsupported parameters:

    properties= {
        landArea={
            type=long
        }, 
        isFurnished={
            type=boolean
        }, isActive={
            type=boolean
        }, title={
            search_analyzer=custom_english_analyzer, 
            analyzer=custom_english_analyzer, 
            type=text
        }, 
        availableFrom={
            type=date
        }, 
        mainPhotoUrl={
            index=false, 
            type=keyword
        }, 
        price={
            type=double
        }, 
        storeName={
            search_analyzer=custom_english_analyzer, 
            analyzer=custom_english_analyzer, 
            type=text
        }, 
        id={
            type=long
        }, 
        firstName={
            search_analyzer=custom_english_analyzer, 
            analyzer=custom_english_analyzer, 
            type=text
        }, 
        geoLocation={
            type=geo_point
        }
    }
}]

您曾经使用过Elasticsearch版本6，现在使用版本7。

我认为您的云Elasticsearch客户端版本仍为版本6。这导致您的错误。在Elasticsearch 7中，映射类型具有被删除。 https://www.elastic.co/guide/en/elasticsearch/reference/6.5/removal-of-types.html

还将您的云升级到版本7。
