How to search inside multiple indices using Nest ElasticSearch?

由 人盡茶涼 提交于 2019-12-10 10:20:01
问题 I have two indices with the following mapping(I will shortcut their mappings): 1) AccountType mapping: elasticClient.CreateIndex("account", i => i .Settings(s => s .NumberOfShards(2) .NumberOfReplicas(0) ) .Mappings(m => m .Map<AccountType>(map => map .AutoMap() .Properties(p => p .Text(c => c .Name(n => n.Name) .Analyzer("standard") ) .Text(c => c .Name(n => n.Description) .Analyzer("standard") ) ) ) ) ); 2) ProductType mapping: elasticClient.CreateIndex("proudct", i => i .Settings(s => s

load specific fields in Elasticsearch Nest query

问题 the documentation seems to indicate i can return a subset of fields instead of the entire document. here's my code: var result = client.Search<MyObject>(s => s .Fields(f => f.Title) .Query(q => q .QueryString(qs => qs .OnField("title") .Query("the")))); i'm searching on the word 'the' on the 'title' field and wanting to just return 'title'. my result.Documents object contains 10 objects that are each null. i do see the values i want but it's deep in the search response: result.Hits[0].Fields

问题 I want to do a search matching multiple values ( an array of values ) like this : var result1 = _client.Search<type1>(s => s .Fields(f => f.trip_id) .Query(q => q .Terms(t => t.arg1, value1)).Take(_allData)) .Documents.Select(d => d.arg2).ToArray(); var result2 = _client.Search<type2>(s => s .Query(q => q .Terms(t => t.arg3, result1)) .Take(_allData) ).Documents.Select(s => s.ar3).ToList(); How can I do ? I was thinking about facets but I don't see how I can do it. The only way for now that

Matching a complete complex nested collection item instead of separate members with Elastic Search

由 好久不见. 提交于 2019-12-09 23:55:48
问题 I have an index with a nested collection of items I want to hit. A collection item contains multiple properties that all have to match a certain query, not just any of them. Here's the model: public class IndexEntry1 { public IEnumerable<NestedType1> NestedProperty1 { get; set; } } public class NestedType1 { public string Member1 { get; set; } public string Member2 { get; set; } } So I want to hit only documents that have a specific combination of Member1 and Member2 values in the IndexEntry1

How do I map a single .NET type to multiple nested object types in ElasticSearch/NEST?

由 这一生的挚爱 提交于 2019-12-09 02:19:51
问题 I'm using the NEST library to interact with ElasticSearch, and I'm trying to figure out a way to build index types/nested objects based on non-type data. The type has the following basic structure. public class Entity : DynamicObject { public string Id { get; set; } // a bunch of other simple properties public override IEnumerable<string> GetDynamicMemberNames() { return Data.Select(x => x.Name); } public override bool TryGetMember(GetMemberBinder binder, out object result) { var dictionary =

Copying a nested property to parent object in elasticsearch with Nest client

由 血红的双手。 提交于 2019-12-08 12:21:07
问题 How can I copy a nested property into a field of the containing POCO in an index mapping definition? I am able to successfully copy a property into another property with .CopyTo when both fields are at the same object level. However I am struggling with copying a property on a nested object into a property on the parent object. Given the objects below, I would like to copy 'Street' from the Address property on a Person into the 'Search' property on Person Person { public string Search { get;

AddSortField in nest 2 upgrade

由 冷暖自知 提交于 2019-12-08 11:19:04
问题 I used to use the add-sort-field=true as an attribute to a property, but with the new nest I can't find the equivalent. Where is it? Thanks. 回答1: Looks like it has been accidently removed from NEST 2.x. I couldn't find any trace why. Feel free to ask this question if you think it was useful in your case. Link to the NEST github. As far I as I understand, property was creating fieldname.sort field which was not_analyzed . For time being you can handle this by explicit creating field.
