Getting an ElasticSearch Cluster to Green (Cluster Setup on OS X)

由 点点圈 提交于 2021-02-05 13:55:09
问题 I have installed ElasticSearch on Mac OS X using Homebrew. It works. The cluster started off with "green" health. However, right after adding data, it has gone to "yellow". The cluster health is status is: green, yellow or red. On the shard level, a red status indicates that the specific shard is not allocated in the cluster, yellow means that the primary shard is allocated but replicas are not, and green means that all shards are allocated. The index level status is controlled by the worst

问题 I'm developing a system which is planning to use elasticsearch as an data repository. I'm trying to choose the best way to develop my application that can index and query data from elasticsearch. The system I have is built on top of Spring framework. Is it a good choice to use Spring-data-elasticsearch (https://github.com/spring-projects/spring-data-elasticsearch)? Or is it a good choice to use elasticsearch core libraries itself ? I need to handle nested data (inner object) but Spring-data

问题 Hi I'm trying to get all results with elasticSearch query, but it returns only 10 results if $limit value is null. $videos = Video::searchByQuery([ 'match' => [ $field => $request->$field ], ],null,null,null); so how to get all results ? 回答1: That's because the default size for requests is 10 and not passing a length limit to any framework is probably going to set it to the default. You can use from and size with large values though: Though from and size can be set as request parameters, they

Multimatch query with Fuzzy NEST - ElasticSearch

问题 I wrote the following query to check multiple fields from a value and it's work: var searchResponse = client.Search<Document>(s => s .Query(q => q .MultiMatch(a => a .Fields(f => f .Field(p => p.Attachment.Content) .Field(p => p.FileName)) .Query(queryValue)))); I would achieve the same result (search the queryValue in fields Attachment.Content and FileName) but with the Fuzzy mechanism (for example, if queryValue is "esting" I would get back also a result with filename "testing"). Thanks a
