How to use X509 certificate with the Nest Elastic Client

阅读更多关于 How to use X509 certificate with the Nest Elastic Client

问题 I am currently upgrading from Elastic Search 1.7 to 5.2. I know there is no upgrade path, which is fine. One problem we had originally is with Nest and ElastiSearch.Net there was no way to attach an X509 certificate as it only had the ability to use Basic Authentication. To get around that we made copies of the existing github repos and modified the code directly to allow it. This ultimately is what kept us from upgrading for so long since we couldn't just use the nuget packages, because we

问题 I use Searchblox to index and search my files, which itself calls ES 2.x to do the job. Searchblox uses a "mapping.json" file to initialize a mapping upon the creation of an index. Here's the link to that file. As "@Russ Cam" suggested here, I created my own class content with the following code (just like he did with the "questions" index and "Question" class): public class Content { public string type { get; set; } public Fields fields { get; set; } } public class Fields { public Content1

ElasticSearch NEST API update value to null

阅读更多关于 ElasticSearch NEST API update value to null

问题 I am using NEST api and I am having trouble using client.Update<T, K> method to update a value to null Is there any parameter or settings when calling update that will allow for null to be set trough nest api? I know I can do it with sense. 回答1: Rather then changing how null should be serialised for the entire request the safest and most isolated way to do this is to introduce a separate POCO for the update where the property you want to clear has the following attribute.
