WebScaNN is an approximate nearest neighbor (ANN) search algorithm. There is an entire zoo of them, but they all have the same goal: given a query vector q and a data matrix X (where q has the same number of elements as a row vector in X ), find the k vectors in X that are “most similar” to q, without exhaustively checking all the possible ... There are well-established data structures for kNN on low-dimensional vectors, like KD-trees. In fact, Elasticsearch incorporates KD-treesto support searches on geospatial and numeric data. But modern embedding models for text and images typically produce high-dimensional vectors of 100 - 1000 … See more Designing ANN algorithms is an active area of academic research, and there are many promising algorithms to choose from. They often present different trade-offs in terms of their search speed, implementation … See more To index vectors for ANN search, we need to set index: true and specify the similarity metric we’re using to compare them: See more

WebWhat Is Elasticsearch? Elasticsearch is a distributed search and analytics engine built on Apache Lucene. Since its release in 2010, Elasticsearch has quickly become the most popular search engine and is commonly used for log analytics, full-text search, security intelligence, business analytics, and operational intelligence use cases. WebThis allows for a simple-to-use, ready-for-production vector similarity search solution that helps preserve end users’ engineering resources. The GSI Elasticsearch k-NN plugin also addresses the previously mentioned scaling and indexing issues seen with many of the open-source vector search libraries because it leverages two of Elasticsearch ...
