A search string can be specified as one of the query parameters to retrieve matching documents. Azure Search supports search strings using simple query syntax. [6] Supported features include logical operators, the suffix operator, and query with Lucene query syntax. [7] (currently in preview) As an example, white+house
Semantic search seeks to improve search accuracy by understanding the searcher's intent and the contextual meaning of terms as they appear in the searchable dataspace, whether on the Web or within a closed system, to generate more relevant results.
A vector database, vector store or vector search engine is a database that can store vectors (fixed-length lists of numbers) along with other data items. Vector databases typically implement one or more Approximate Nearest Neighbor algorithms, [1] [2] [3] so that one can search the database with a query vector to retrieve the closest matching database records.
When Pinecone announced a vector database at the beginning of last year, it was building something that was specifically designed for machine learning and aimed at data scientists.
In cryptography, an initialization vector (IV) or starting variable [1] is an input to a cryptographic primitive being used to provide the initial state. The IV is typically required to be random or pseudorandom , but sometimes an IV only needs to be unpredictable or unique.
It can be used with many repositories such as Apache Solr, Elasticsearch, Microsoft Azure Cognitive Search, Amazon CloudSearch and more. mnoGoSearch is a crawler, indexer and a search engine written in C and licensed under the GPL (*NIX machines only) Open Search Server is a search engine and web crawler software release under the GPL.
Security in terms of indistinguishability has many definitions, depending on assumptions made about the capabilities of the attacker. It is normally presented as a game , where the cryptosystem is considered secure if no adversary can win the game with significantly greater probability than an adversary who must guess randomly.
Goldwasser/Micali subsequently demonstrated that semantic security is equivalent to another definition of security called ciphertext indistinguishability under chosen-plaintext attack. [5] This latter definition is more common than the original definition of semantic security because it better facilitates proving the security of practical ...
