About Apache Solr

Solr is a NoSQL data browser. It was developed by Yonik Seeley in 2007, and it is part of the Lucene project. Solr functions as a browser, and it runs on a server. Solr has a particular way of functioning that you need to understand before diving into its uses or its specific features. First, Solr Indexes the information that is fed into it. It transforms it into a format that can be machine-read. Then, the user inputs a query and the Solr client interprets it. A query can be in the form of keywords or even have the capability of being images. Then, Solr maps the query to the data that is stored within and identifies the proper result. Finally, comes the process of ranking, which is exactly what one might expect when hearing the word. The outputs are ranked per relevance, or likelihood that the query was referring to that document or set of documents in particular. As Solr is a data browser, and not necessarily a server, it can be integrated with other tools like Cassandra, making it a powerful combination that integrates brilliant features from multiple developers.

Solr has uses in many content-related industries, where the data stored can be strings, numbers, etc. But also extremely likely to be stored in the form of text documents, images, among many other formats that these companies may necessitate.

This browser has specific features that set it apart from others. First, the explained four-step process is unique to Solr, and it involves techniques that make it extremely quick for retrieving information, where it can be then analyzed by another piece of software, again pointing to the big integration advantages that come with Solr. Another very interesting feature, maybe not native to the software itself, is that Solr belongs to an Apache project, which means that it is open-source. This is good because Solr has a network of both users and a professional support community that can help solve issues and offer help to anyone that might need it.

Releases

Solr finished development and published its first stable version in 2007, but it underwent development in 2004, where it evolved for two years and was donated to the Apache Software Foundation. The software underwent constant evolution to be where it is today. We are currently on the 8.8.2 version, released on the 12th of April of the present year of 2021. Solr is expected to develop new updates and content, so it is safe to think support and feature development will continue for years to come.
