ElasticSearch and NEST: How do you purge all documents from an index?

由 ♀尐吖头ヾ 提交于 2019-12-30 08:02:05
问题 I know how to delete an entire ElasticSearch index, but how do you purge all documents from an index? My Motivation: I'd like to have a "ReIndex" method that purges the entire contents of an index so that I can reload all documents. ElasticSearch syntax would be helful. NEST syntax would be even better. 回答1: I was looking for something similar in Nest and I thought I'd put the syntax here for anyone looking: var node = new Uri("http://localhost:9200"); var settings = new ConnectionSettings

由 跟風遠走 提交于 2019-12-30 04:49:29
问题 I would like to use Nest to populate the completion suggestion field into an index. After reading this ElasticSearch blog post about implementing a completion field I see you can have the following properties: array of inputs single output weight payload I am assuming that to load this data into an index I need to include an entity on my search object that contains the above fields? 回答1: I was able to finally load the completion field by creating several classes, and following the

由 可紊 提交于 2019-12-29 01:53:08
问题 want to build the auto complete functionality of an e-commerce website, using Completion Suggester. This is my Index: PUT myIndex { "mappings": { "_doc" : { "properties" : { "suggest" : { "type" : "completion" }, "title" : { "type": "keyword" }, "category" : { "type": "keyword" }, "description" : { "type": "keyword" } } } } } Now, when uploading the advertisement I want the title field to be used for auto complete, so this is how I upload a document: POST dummy/_doc { "title": "Blue asics

ElasticSearch NEST Query

由 北城以北 提交于 2019-12-28 13:56:52
问题 I'm trying to mimic a query that I wrote in Sense (chrome plugin) using NEST in C#. I can't figure out what the difference between the two queries is. The Sense query returns records while the nest query does not. The queries are as follows: var searchResults = client.Search<File>(s => s.Query(q => q.Term(p => p.fileContents, "int"))); and { "query": { "term": { "fileContents": { "value": "int" } } } What is the difference between these two queries? Why would one return records and the other

Elastic search with GUID ID without attributes

由 ∥☆過路亽．° 提交于 2019-12-25 09:17:11
问题 We are looking to switch from a relational database to elastic search and I am trying to get some basic code up and running with Nest. We have existing objects which use guids for ids that I would like to save into an elastic search index. I don't want to add any specific attributes as the class is used in different applications and I don't want to add unnecessary dependencies to Nest. Right now my code looks like this: var node = new Uri("http://localhost:9200"); var settings = new

Elasticsearch and NEST: Filtering with Lookups

由 [亡魂溺海] 提交于 2019-12-25 06:58:11
问题 I'm using Elasticsearch 1.7.x (and NEST 1.7.2) and trying to take advantage of filtering with lookups as documented here: Terms Filter Lookup. I'm able to craft the JSON by hand for the request I desire and execute it using Sense. Works great, awesome feature! However, in the NEST library, I don't see a way to create such a terms clause. For example, from the link referenced above, I can do something like: "terms" : { "proteins" : { "index" : "microarrays", "type" : "experiment", "id" :

问题 I need to search for files and folder with in specific directories. In order to do that, elastic asks us to create the analyzer and set the tokenizer to path_hierarchy PUT /fs { "settings": { "analysis": { "analyzer": { "paths": { "tokenizer": "path_hierarchy" } } } } } Then, create the mapping as illustrated below with two properties: name (holding the name of the file) and path (to store the directory path): PUT /fs/_mapping/file { "properties": { "name": { "type": "string", "index": "not
