What is the principle of inverse index in Spanish?

Inverted index is a data structure used for quickly finding all documents in a collection that contain a specific word. It works by mapping each word in the document set to a list of documents that contain that word, creating an index table where words are keys and document lists are values. When searching for a word, one can simply locate the corresponding document list in the index table to quickly find all documents containing that word. Inverted indexes are commonly used in applications such as search engines that require efficient retrieval of text information.
