Databases & Data Storage
NoSQL Search Database
Definition
A search database is a specialized type of NoSQL database optimized for full-text search and analysis of large volumes of text-based or other unstructured data. It uses an inverted index to provide fast query responses.
Why It Matters
Standard databases are not efficient for text search. Search databases provide the powerful and fast search capabilities needed for modern applications, from website search bars to complex log analytics.
Contextual Example
Elasticsearch and OpenSearch are leading examples of search databases. They are used to power product search on e-commerce sites, search through application logs, and analyze security event data.
Common Misunderstandings
- They are a subtype of NoSQL database, often categorized as "search engines".
- The core data structure that makes them fast is the inverted index.
