nest

问题 Short version: I would like to write an elastic search query using Nest to get the full indexed items ( ContentIndexables in my case as my custom type) which have been indexed. The query is subject to a term query of [some string] + * (i.e. String.StartsWith() where [some string] may or may not contain spaces. This is different to CompletionSuggester since I need to retrieve the full object and not string suggestions. What I've tried so far: When I query for a text without spaces, the desired

问题 I am using ElasticSearch via NEST c#. I have large list of information about people { firstName: 'Frank', lastName: 'Jones', City: 'New York' } I'd like to be able to filter and sort this list of items by lastName as well as order by the length so people who only have 5 characters in their name will be at the beginning of the result set then people with 10 characters. So with some pseudo code I'd like to do something like list.wildcard("j*").sort(m => lastName.length) I'm new to ElasticSearch

问题 I am new to ElasticSearch - NEST API. We are trying to prepare multiple conditions with AND/OR clauses. For example - (Condition 1 OR Condition 2) AND (Condition 3) Currently we are trying by concatenating the query conditions. Can anyone provide the better example using NEST API? 回答1: Well there is something called Bool Query in ElasticSearch. A query that matches documents matching boolean combinations (AND, OR, NOT) of other queries. It is built using one or more boolean clauses, each

问题 I have an array or objects consisting of a date and some values: var flatData = [ { "date": "2012-05-26", "product": "apple" }, { "date": "2012-07-03", "product": "orange" }, ... ] I am trying to use d3.nest() to get a count of these objects by year and then by month. var nestedData = d3.nest() .key(function(d) { return d.date.split('-')[0]; }) // key is the year .sortKeys(d3.ascending) .key(function(d) { var splitDate = d.date.split('-'); return splitDate[0] + '-' + splitDate[1]; // key is

问题 I have noticed a lot of changes in ES after upgrading it from v1.9 to v5.4. I am still having doubts about the querying techniques in ES. In v1.9 I have noticed that the Filter option differs. I am wondering how I can replicate the below code in v5.4 searchDescriptor.Query(q => q.Filtered(m => m.Query(n => matchQuery).Filter(o => o.And(filterContainer.ToArray())))) Here I see Filter(o => o.And(filterContainer.ToArray()) how is it possible to do an And or an Or operation with v5.4? Does Filter

问题 I'm using Nest to insert a list of 60k+ objects into elastic search, specifically calling client.IndexMany(list, indexName). As the list is inserted, is it query-able? or is it only query-able after the complete list is indexed? If its the former, is there a way to force it to only be query-able after the list is fully indexed? 回答1: Ad1. The answer is no. Document isn't immediately available for search after indexing. Definitive guide has really nice chapter why elasticsearch works this way.

问题 I have an index with many fields, and one field "ServiceCategories" has data similar to this: |Case Management|Developmental Disabilities I need to break up the data by the separator "|" and I have attempted to do so with this: var descriptor = new CreateIndexDescriptor(_DataSource.ToLower()) .Mappings(ms => ms .Map<ProviderContent>(m => m .AutoMap() .Properties(p => p .String(s => s .Name(n => n.OrganizationName) .Fields(f => f .String(ss => ss.Name("raw").NotAnalyzed()))) .String(s => s

问题 I am querying ElasticSearch with Nest, with this code: var mustTerms = new List<Func<QueryDescriptor<ElasticCheckIn>, Nest.QueryContainer>>(); var dmaxPrice = maxPrice.HasValue ? (double?)maxPrice.Value : 100000d; var dminPrice = minPrice.HasValue ? (double?)minPrice.Value : 0d; mustTerms.Add(mt => mt.Range(rd => rd.OnField("price").LowerOrEquals(dmaxPrice).GreaterOrEquals(dminPrice))); Func<QueryDescriptor<ElasticCheckIn>, Nest.QueryContainer> queryFunc = qd => qd .FunctionScore(fsq => fsq

问题 I'm trying to reproduce a console application which watches a folder and any new additions of documents to the folder are to be Indexed to ES . It is working fine If I move/add 3-4 documents at a time and able to index. But if I move around 30 documents at a time, It is not indexing all the documents, instead indexing only one. But If I run the code with break points , then even 30 documents are also getting indexed. Can some one help me in solving this. static void OnCreated(object sender,

问题 I am using following code for searching the articleid and control fields. it will hold the 2 fields values. But I can't access these two fields values. HERE search<> is dynamic. var searchrange = _client.Search<dynamic>(s => s .Indices("kb_v2").Types("kb") .From(0).Size(10) .Fields("articleid","control") .Query(q => q .Range(r =>r .OnField("articleid") .Greater("2") .Lower("5")))); can you explain How to get the this two fields values.. 回答1: Since Elasticsearch 1.0 fields are always returned
