Indexer
An **indexer** is a person, software program, or hardware device responsible for creating and maintaining an index. This process typically involves analyzing a large collection of data (e.g., text documents, web pages, database records) to extract relevant keywords, phrases, or attributes. These extracted elements are then organized and structured into an index, allowing for efficient searching and retrieval of information. The indexer streamlines access to specific information, enabling rapid access to data from large sets. Effective indexers employ various algorithms and techniques, such as stemming, stop-word removal, and entity recognition, to improve the accuracy and speed of information retrieval. The output of an indexer facilitates effective and efficient search and navigation across vast datasets.
