Sonic Server vs Sphinx: What are the differences?

What is Sonic Server? Fast, lightweight & schema-less search backend. A fast, lightweight and schema-less search backend. It ingests search texts and identifier tuples that can then be queried against in microseconds.

What is Sphinx? Open source full text search server, designed from the ground up with performance, relevance (aka search quality), and integration simplicity in mind. Sphinx lets you either batch index and search data stored in an SQL database, NoSQL storage, or just files quickly and easily — or index and search data on the fly, working with Sphinx pretty much as with a database server. A variety of text processing features enable fine-tuning Sphinx for your particular application requirements, and a number of relevance functions ensures you can tweak search quality as well.

Sonic Server and Sphinx belong to "Search Engines" category of the tech stack.

Some of the features offered by Sonic Server are:

• Search terms are stored in collections, organized in buckets

- Search results return object identifiers

On the other hand, Sphinx provides the following key features:

• Output formats: HTML (including Windows HTML Help), LaTeX (for printable PDF versions), ePub, Texinfo, manual pages, plain text
• Extensive cross-references: semantic markup and automatic links for functions, classes, citations, glossary terms and similar pieces of information
• Hierarchical structure: easy definition of a document tree, with automatic links to siblings, parents and children
