我已经创建了elasticsearch和Solr和splunk之间的主要差异表，您可以使用它作为2016年的更新:

由于Apache Solr的悠久历史，我认为Solr的一个优势是它的生态系统。针对不同类型的数据和用途，有许多Solr插件。

搜索平台从下到上分为以下几层:

数据 目的:表示各种数据类型和来源 文档建立 目的:为索引建立文档信息 索引和搜索 目的:建立和查询文档索引 逻辑增强 用途:用于处理搜索查询和结果的附加逻辑 搜索平台服务 目的:增加搜索引擎核心的附加功能，提供服务平台。 UI应用程序 用途:用于终端用户搜索界面或应用程序

While all of the above links have merit, and have benefited me greatly in the past, as a linguist "exposed" to various Lucene search engines for the last 15 years, I have to say that elastic-search development is very fast in Python. That being said, some of the code felt non-intuitive to me. So, I reached out to one component of the ELK stack, Kibana, from an open source perspective, and found that I could generate the somewhat cryptic code of elasticsearch very easily in Kibana. Also, I could pull Chrome Sense es queries into Kibana as well. If you use Kibana to evaluate es, it will further speed up your evaluation. What took hours to run on other platforms was up and running in JSON in Sense on top of elasticsearch (RESTful interface) in a few minutes at worst (largest data sets); in seconds at best. The documentation for elasticsearch, while 700+ pages, didn't answer questions I had that normally would be resolved in SOLR or other Lucene documentation, which obviously took more time to analyze. Also, you may want to take a look at Aggregates in elastic-search, which have taken Faceting to a new level.

Bigger picture: if you're doing data science, text analytics, or computational linguistics, elasticsearch has some ranking algorithms that seem to innovate well in the information retrieval area. If you're using any TF/IDF algorithms, Text Frequency/Inverse Document Frequency, elasticsearch extends this 1960's algorithm to a new level, even using BM25, Best Match 25, and other Relevancy Ranking algorithms. So, if you are scoring or ranking words, phrases or sentences, elasticsearch does this scoring on the fly, without the large overhead of other data analytics approaches that take hours--another elasticsearch time savings. With es, combining some of the strengths of bucketing from aggregations with the real-time JSON data relevancy scoring and ranking, you could find a winning combination, depending on either your agile (stories) or architectural(use cases) approach.

注意:上面确实有关于聚合的类似讨论，但没有关于聚合和相关性评分的讨论——我为任何重叠道歉。 披露:我不为elastic工作，而且由于不同的架构路径，在不久的将来也无法从他们的出色工作中受益，除非我用elasticsearch做一些慈善工作，这也不是一个坏主意

我看到这里有很多人回答了ElasticSearch和Solr在特性和功能方面的问题，但我在这里(或其他地方)没有看到太多关于它们在性能方面如何比较的讨论。

这就是我决定自己进行调查的原因。我采用了一个已经编码的异构数据源微服务，该服务已经使用Solr进行术语搜索。我把Solr换成了ElasticSearch，然后在AWS上用一个已经编码的负载测试应用程序运行了两个版本，并捕获了用于后续分析的性能指标。

以下是我的发现。在索引文档时，ElasticSearch的吞吐量要高13%，而Solr的速度要快10倍。在文档查询方面，Solr的吞吐量是ElasticSearch的5倍，速度也是ElasticSearch的5倍。
