large search indexes split over thousands of search buckets per collection. An IID (ie. Internal-ID) is stored in the index as a 32 bits number, which theoretically allow up to ~4.2 billion objects to be indexed (ie. OID) per bucket. We've observed storage savings of 30% to 40%, which justifies the trade-off on large databases (versus Sonic using 64 bits IIDs). Also, Sonic only keeps the N most recently pushed results for a given word, in a sliding window way (the sliding window width can be configured).\u003c/li\u003e\n\u003cli\u003e\u003cstrong\u003eSearch query limits\u003c/strong\u003e: Sonic Natural Language Processing system (NLP) does not work at the sentence-level, for storage compactness reasons (we keep the FST graph shallow as to reduce time and space complexity). It works at the word-level, and is thus able to search per-word and can predict a word based on user input, though it is unable to predict the next word in a sentence.\u003c/li\u003e\n\u003cli\u003e\u003cstrong\u003eReal-time limits\u003c/strong\u003e: the FST needs to be rebuilt every time a word is pushed or popped from the bucket graph. As this is quite heavy, Sonic batches rebuild cycles. If you have just pushed a new word to the index and you are not seeing it in the \u003ccode\u003eSUGGEST\u003c/code\u003e command yet, wait for the next rebuild cycle to kick-in, or force it with \u003ccode\u003eTRIGGER consolidate\u003c/code\u003e in a \u003ccode\u003econtrol\u003c/code\u003e channel.\u003c/li\u003e\n\u003cli\u003e\u003cstrong\u003eInteroperability limits\u003c/strong\u003e: The Sonic Channel protocol is the only way to read and write search entries to the Sonic search index. Sonic does not expose any HTTP API. Sonic Channel has been designed with performance and minimal network footprint in mind.

schema-less search backend. It ingests search texts and identifier tuples that can then be queried against in a microsecond's time.</strong></p> <p dir="auto">Sonic can be used as a simple alternative to super-heavy and full-featured search backends such as Elasticsearch in some use-cases. It is capable of normalizing natural language search queries, auto-completing a search query and providing the most relevant results for a query. Sonic is an identifier index, rather than a document index; when queried, it returns IDs that can then be used to refer to the matched documents in an external database.</p> <p dir="auto">A strong attention to performance and code cleanliness has been given when designing Sonic. It aims at being crash-free, super-fast and puts minimum strain on server resources (our measurements have shown that Sonic - when under load - responds to search queries in the μs range, eats ~30MB RAM and has a low CPU footprint; <a href="https://github.com/valeriansaliou/sonic#how-fast--lightweight-is-it">see our benchmarks</a>).</p> <p dir="auto"><em>Tested at Rust version: <code>rustc 1.74.1 (a28077b28 2023-12-04)</code></em></p> <p dir="auto"><strong>🇫🇷 Crafted in Nantes, France.</strong></p> <p dir="auto"><strong>📰 The Sonic project was initially announced in <a href="https://journal.valeriansaliou.name/announcing-sonic-a-super-light-alternative-to-elasticsearch/" rel="nofollow">a post on my personal journal</a>.</strong></p> <p dir="auto"><a target="_blank" rel="noopener noreferrer nofollow" href="https://camo.githubusercontent.com/3b9f9ef1f4becd80d9a662500cb13759166cda6ca894db2bf084a06863d5d543/68747470733a2f2f76616c657269616e73616c696f752e6769746875622e696f2f736f6e69632f696d616765732f62616e6e65722e6a7067"><img src="https://camo.githubusercontent.com/3b9f9ef1f4becd80d9a662500cb13759166cda6ca894db2bf084a06863d5d543/68747470733a2f2f76616c657269616e73616c696f752e6769746875622e696f2f736f6e69632f696d616765732f62616e6e65722e6a7067" alt="Sonic" data-canonical-src="https://valeriansaliou.github.io/sonic/images/banner.jpg" style="max-width: 100%;"></a></p> <blockquote> <p dir="auto"><em>« Sonic » is the mascot of the Sonic project.

buckets per collection. An IID (ie. Internal-ID) is stored in the index as a 32 bits number, which theoretically allow up to ~4.2 billion objects to be indexed (ie. OID) per bucket. We've observed storage savings of 30% to 40%, which justifies the trade-off on large databases (versus Sonic using 64 bits IIDs). Also, Sonic only keeps the N most recently pushed results for a given word, in a sliding window way (the sliding window width can be configured).</li> <li><strong>Search query limits</strong>: Sonic Natural Language Processing system (NLP) does not work at the sentence-level, for storage compactness reasons (we keep the FST graph shallow as to reduce time and space complexity). It works at the word-level, and is thus able to search per-word and can predict a word based on user input, though it is unable to predict the next word in a sentence.</li> <li><strong>Real-time limits</strong>: the FST needs to be rebuilt every time a word is pushed or popped from the bucket graph. As this is quite heavy, Sonic batches rebuild cycles. If you have just pushed a new word to the index and you are not seeing it in the <code>SUGGEST</code> command yet, wait for the next rebuild cycle to kick-in, or force it with <code>TRIGGER consolidate</code> in a <code>control</code> channel.</li> <li><strong>Interoperability limits</strong>: The Sonic Channel protocol is the only way to read and write search entries to the Sonic search index. Sonic does not expose any HTTP API. Sonic Channel has been designed with performance and minimal network footprint in mind. If you need to access Sonic from an unsupported programming language, you can either <a href="https://github.com/valeriansaliou/sonic/issues/new">open an issue</a> or look at the reference <a href="https://github.com/valeriansaliou/node-sonic-channel">node-sonic-channel</a> implementation and build it in your target programming language.</li> <li><strong>Hardware limits</strong>: Sonic performs the search on the file-system directly; ie. it does not fit the index in RAM. A search query results in a lot of random accesses on the disk, which means that it will be quite slow on old-school HDDs and super-fast on newer SSDs. Do store the Sonic database on SSD-backed file systems only.</li> </ul> <div class="markdown-heading" dir="auto"><h2 tabindex="-1" class="heading-element" dir="auto">🔥 Report A Vulnerability</h2><a id="user-content-fire-report-a-vulnerability" class="anchor" aria-label="Permalink: :fire: Report A Vulnerability" href="#fire-report-a-vulnerability"><svg class="octicon octicon-link" viewBox="0 0 16 16" version="1.1" width="16" height="16" aria-hidden="true"><path d="m7.775 3.275 1.25-1.25a3.5 3.5 0 1 1 4.95 4.95l-2.5 2.5a3.5 3.5 0 0 1-4.95 0 .751.751 0 0 1 .018-1.042.751.751 0 0 1 1.042-.018 1.998 1.998 0 0 0 2.83 0l2.5-2.5a2.002 2.002 0 0 0-2.83-2.83l-1.25 1.25a.751.751 0 0 1-1.042-.018.751.751 0 0 1-.018-1.042Zm-4.69 9.64a1.998 1.998 0 0 0 2.83 0l1.25-1.25a.751.751 0 0 1 1.042.018.751.751 0 0 1 .018 1.042l-1.25 1.25a3.5 3.5 0 1 1-4.95-4.95l2.5-2.5a3.5 3.5 0 0 1 4.95 0 .751.751 0 0 1-.018 1.042.751.751 0 0 1-1.042.018 1.998 1.998 0 0 0-2.83 0l-2.5 2.5a1.998 1.998 0 0 0 0 2.83Z"></path></svg></a></div> <p dir="auto">If you find a vulnerability in Sonic, you are more than welcome to report it directly to <a href="https://github.com/valeriansaliou">@valeriansaliou</a> by sending an encrypted email to <a href="mailto:valerian@valeriansaliou.name">valerian@valeriansaliou.name</a>.
