我有2种类型的一个指数,都具有推荐领域(如需要)Elasticsearch建议是合并两种
public class LegalAreaSearchModel : LegalAreaModel
{
public SuggestField Suggest
{
get
{
List<string> input = new List<string>();
string[] childArea = !string.IsNullOrEmpty(this.LegalArea) ? this.LegalArea.Split(' ') : new string[] { "" };
string[] ParentArea = !string.IsNullOrEmpty(this.Parent) ? this.Parent.Split(' ') : new string[] { "" };
input.AddRange(childArea);
input.AddRange(ParentArea);
return
new SuggestField
{
Input = input,
Output = this.LegalArea,
Payload = new
{
Id = this.RowId,
Name = !string.IsNullOrEmpty(this.Parent) ? this.Parent + "/" + this.LegalArea : this.LegalArea,
Type = "Specialization"
},
Weight = !string.IsNullOrEmpty(this.LegalArea) ? this.LegalArea.Length : 0
};
}
}
}
和
public class LegalDocumentSearchModel : LegalDocumentModel
{
public LegalDocumentSearchModel()
{
//this = ObjectCopier.Clone<LegalDocumentSearchModel>(legalDocumentSearchModel);
SupplierDetails = new List<LegalDocumentSupplierDetailForSearch>();
CategoryDetails = new List<CategoryDetails>();
}
[Nested()]
public List<LegalDocumentSupplierDetailForSearch> SupplierDetails { get; set; }
[Nested()]
public List<CategoryDetails> CategoryDetails { get; set; }
public SuggestField Suggest
{
get
{
return
new SuggestField
{
Input = new List<string>(!string.IsNullOrEmpty(this.Name) ? this.Name.Split(' ') : new string[] { "" }) { this.Name },
Output = this.Name,
Payload = new
{
Id = this.RowId,
SEOFriendlyURLName = !string.IsNullOrEmpty(this.SEOFriendlyURLName) ? string.Concat(this.SEOFriendlyURLName) : string.Empty,
Name = this.Name,
ProductType = this.ProductType,
Description = this.Description
},
Weight = !string.IsNullOrEmpty(this.Description) ? this.Description.Length : 0
};
}
}
}
public class LegalDocumentSupplierDetailForSearch
{
public string PinCode { get; set; }
public string Lattitude { get; set; }
public string Longitude { get; set; }
}
public class CategoryDetails
{
public int CategoryId { get; set; }
public string CategoryName { get; set; }
}
现在的结果我的搜索如下
List<AdvocateListingSuggestionModel> lsResult = new List<AdvocateListingSuggestionModel>();
var result = _searchProvider.Client.Suggest<LegalAreaSearchModel>(s => s
.Index(SearchConfigurationManager.DefaultSearchIndex)
.Completion("ml-la-suggestions", c => c
.Text(Search)
.Field(p => p.Suggest)
.Fuzzy(fz => fz
.Fuzziness(Fuzziness.Auto))
)
);
我从其他类型也得到结果(混合)我们如何限制只有一种类型的结果
Type1.LegalAreaSearchModel 类型2.LegalDocumentSearchModel
我的索引是如下
public static bool CheckForIndex(ElasticSearchProvider searchProvider)
{
Nest.IndexExistsRequest idr = new Nest.IndexExistsRequest(Nest.Indices.Index(new Nest.IndexName() { Name = SearchConfigurationManager.DefaultSearchIndex }));
var indxres = searchProvider.Client.IndexExists(idr);
if (!indxres.Exists)
{
searchProvider.Client.CreateIndex(SearchConfigurationManager.DefaultSearchIndex, i => i
.Settings(s => s
.NumberOfShards(2)
.NumberOfReplicas(0)
.Analysis(analysis => analysis
.Tokenizers(tokenizers => tokenizers
.Pattern("ml-id-tokenizer", p => p.Pattern(@"\W+"))
)
.TokenFilters(tokenfilters => tokenfilters
.WordDelimiter("ml-id-words", wd => wd
.SplitOnCaseChange()
.PreserveOriginal()
.SplitOnNumerics()
.GenerateNumberParts(false)
.GenerateWordParts()
)
)
.Analyzers(analyzers => analyzers
.Custom("ml-id-analyzer", c => c
.Tokenizer("ml-id-tokenizer")
.Filters("ml-id-words", "lowercase")
)
.Custom("ml-id-keyword", c => c
.Tokenizer("keyword")
.Filters("lowercase")
)
)
)
));
}
return true;
}
Creatining文件类型如下
public bool CreateDocumentIndex()
{
bool retVal = false;
if (Common.CheckForIndex(_searchProvider))
{
var res = _searchProvider.Client.Map<LegalDocumentSearchModel>(m =>
m.Index(SearchConfigurationManager.DefaultSearchIndex)
.Type(this.type)
.AutoMap()
.Properties(ps => ps
.String(s => s
.Name(p => p.Id)
.Analyzer("ml-id-analyzer")
.Fields(f => f
.String(p => p.Name("keyword").Analyzer("ml-id-keyword"))
.String(p => p.Name("raw").Index(FieldIndexOption.NotAnalyzed))
)
)
.Completion(c => c
.Name(p => p.Suggest)
.Payloads()
)
));
retVal = res.IsValid;
}
return retVal;
}
创建LegalArea类型如下
public bool CreateLegalAreaIndex()
{
bool retVal = false;
if (Common.CheckForIndex(_searchProvider))
{
var res = _searchProvider.Client.Map<LegalAreaSearchModel>(m =>
m.Index(SearchConfigurationManager.DefaultSearchIndex)
.Type(this.type)
.AutoMap()
.Properties(ps => ps
.String(s => s
.Name(p => p.Id)
.Analyzer("ml-id-analyzer")
.Fields(f => f
.String(p => p.Name("keyword").Analyzer("ml-id-keyword"))
.String(p => p.Name("raw").Index(FieldIndexOption.NotAnalyzed))
)
)
.Completion(c => c
.Name(p => p.Suggest)
.Payloads()
)
));
retVal = res.IsValid;
}
return retVal;
}
现在,当我运行的法律领域的建议如下
public List<AdvocateListingSuggestionModel> LegalAreaSuggestion(string Search)
{
List<AdvocateListingSuggestionModel> lsResult = new List<AdvocateListingSuggestionModel>();
var result = _searchProvider.Client.Suggest<LegalAreaSearchModel>(s => s
.Index(SearchConfigurationManager.DefaultSearchIndex)
.Completion("ml-la-suggestions", c => c
.Text(Search)
.Field(p => p.Suggest)
.Fuzzy(fz => fz
.Fuzziness(Fuzziness.Auto))
)
);
if (result.IsValid)
{
lsResult = result.Suggestions["ml-la-suggestions"]
.FirstOrDefault()
.Options
.Select(suggest => suggest.Payload<AdvocateListingSuggestionModel>()).ToList();
}
return lsResult;
}
我得到LegalDocumentSearchModel的结果well.pls建议

什么您使用的是NEST版本,您使用的是哪种版本的Elasticsearch? –
Nest 2.1.0和Elasticsearch 2.3 –
@RussCam任何解决方案? –
