Solr is a top-level open-source project under Apache developed using Java. It is a full-text search Server Based on Lucene. Solr provides a richer query language than Lucene, supports configuration and scalability, an
Find a lot of information about SOLR on the web and find it very incomplete, even in the official wiki.
Based on the SOLR application being researched at this stage, I will share some of my experience.

Working Mechanism of ElasticSearch
Like Solr, ElasticSearch is an enterprise-level search engine that is based on Apache Lucene and has high reliability.
Some concepts in ElasticSearch correspond to relational databases. For example, a database is called an index in ES and a table is called a Type in ES.

The loggly Log Management Service uses Elasticsearch as a search engine in many of its core functions. In his article "ElasticSearch vs SOLR", Jon Gifford noted that the field of log management has a higher demand for search technology. In general, it must be able to:

Again, before we go back to the artboard, we rethink how to make an excellent search function within 2012 years. We want to make the search the best feature of kiln and make it a gold-plated brand that people will discuss enthusiastically. After research, we targeted two different but seemingly similar two search engines: Elasticsearch and Apache,
Unlike testing and research, it needs to be installed as a service if it is to be deployed as a product of SOLR. There is a script install_solr_service.sh under the bin directory in the SOLR compression package, which is responsible for the installation of SOLR and is registered as a self-initiated service.Directory Planning:Dynamic Files: It is recommended to pu
