Solr:
Advantages
1. SOLR has a larger, more mature user, development and contributor community.
2, support the addition of multiple formats of the index, such as: HTML, PDF, Microsoft Office series software format, as well as JSON, XML, CSV and other plain text format.
3, SOLR more mature and stable.
4, do not consider the index to search at the same time, faster.
Disadvantages
When indexing is established, search efficiency decreases and real-time index search efficiency is not high.
Elasticsearch
Advantages
1, Elasticsearch is distributed. No other components are needed, the distribution is real-time and is called a "Push replication".
2. Elasticsearch fully supports the near real-time search of Apache Lucene.
3. Handling multiple Tenants (multitenancy) does not require a special configuration, and SOLR requires more advanced settings.
4, Elasticsearch using the concept of Gateway, so that complete more simple.
5, each node constitutes an equivalent network structure, some nodes will automatically assign other nodes in lieu of their work.
Disadvantages
1, not enough automatic, not suitable for the current new index warmup API (reference: http://zhaoyanblog.com/archives/764.html)
Summarize:
1. When a simple search of existing data, SOLR is faster.
2, when the real-time indexing, SOLR will produce IO blocking, poor query performance, Elasticsearch has obvious advantages.
3. With the increase of data volume, SOLR's search efficiency will become lower, but Elasticsearch has not changed significantly.
4, SOLR architecture is not suitable for real-time search applications.
5. SOLR supports more format data, while Elasticsearch only supports JSON file format
6. SOLR performed better than Elasticsearch in traditional search applications, but the time limit for processing real-time search applications was significantly lower than that of Elasticsearch
7. SOLR is a powerful solution for traditional search applications, but Elasticsearch is more suitable for new real-time search applications
