One of the most challenging concepts for growing business is to keep all of their documents organized in one location.

This can make it difficult when developing large apps in which each file needs to be together in order for it to work.

Fortunately, Sphinx and Solr help development teams solve this problem, and we’ll explain their differences later on in this Sphinx vs Solr guide.


What is Sphinx?

Sphinx Search

Sphinx is a Python-based documentation software which can help document multiple software projects in multiple languages.

It was created by Georg Brandl, and is used to make beautiful and intelligent documentation. Here are the main features that Sphinx provides:

  • Hierarchical structure: Sphinx allows you to define a document tree easily, it has automatic links to parents, children, and sibling document trees.
  • Automatic indices: Sphinx also has a language-specific and general module indices
  • Output formats: ePub, HTML, plain text, manual pages, LaTeX, AND Texinfo.


What is Solr?

Solr Search

Apache Solr, also known as Solr is a search platform that’s created by a Java library named Lucene. It’s a popular search platform for large websites because it searches and indexes multiple sites and gives recommendations for content depending on the user’s search query.

It’s a great search platform for enterprise search options as it can search and index email attachments and documents.

  • Real-time indexing
  • Multiple search index
  • Rich document indexing and parsing
  • Server statistics logging
  • Automated index replication

Solr works with Extensible Markup Language (XML) and Hypertext Transfer Protocol (HTTP). And, it allows APIs for Pythons, Thus, is a versatile documentation system that you can use to utilize your company’s public and private servers.


What Makes Them Similar?

Search Spelled out from scrabble game

  • Both Sphinx and Solr were made to satisfy user requirements. They’re designed to search and index large volumes of data efficiently.
  • Both have client bindings in multiple languages/platforms (Solr, Sphinx)
  • Similarities
  • Both Solr and Sphinx satisfy all of your requirements. They’re fast and designed to index and search large bodies of data efficiently.
  • Both have a long list of high-traffic sites using them (Solr, Sphinx).



Here are some of the most obvious differences between both documentation software platforms:

  • Solr has a spell checker to help improve the grammar and quality of the documentation.
  • Solr can be embedded in Java applications.
  • Sphinx is a GPLv2 licensed project while Solr is an Apache2 project.
  • Solr can be moved implemented into Hadoop to make distributed applications.
  • Sphinx doesn’t give users the ability to partially update their data.

When deciding on which platform to choose, it depends on how you need your files documented. For example, use Sphinx when you need a strict system that uses unique keys to prevent documents from becoming duplicated.

Use Solr if you want a limitless documentation system where you can have duplicates and maintain the quality of each of them. No matter which one you choose, you’ll have a reliable system that will help you better manage the documents within your network.



When it comes to sphinx vs solr, it’s hard to tell which one is the winner. It depends on which one is easier for your enterprise to use. Overall, try both frameworks to see which one suits your needs the most!
