Elasticsearch Fundamentals: Indexing and Querying Data

# Term query

A term query is a type of query used to search for documents containing an exact term or value in a specific field. It is designed for searching `keyword` fields, which are stored in the inverted index without any analysis or tokenization. Term queries are particularly useful for exact matches, such as searching for a product ID or username, where an exact match is necessary. 

Learn about the term query and how to use it.
