Indekso

Indekso is a term used in several languages to denote an index or indicator. The word is used across disciplines to refer to a systematic reference that helps locate information, track changes, or summarize a collection of items. Depending on context, it can refer to a list, a data structure, a statistical measure, or a sign used to identify a concept.

In libraries and publishing, an index is a structured list of topics, names, or terms with pointers to where they appear in a text or document. Book indices guide readers to specific subjects, names, or places, while bibliographic indices help organize references for research.

In information retrieval and computing, an index is a data structure that enables fast lookups. Database indexes, search engine indexes, and inverted indexes are built on searchable keys to speed data retrieval and improve query efficiency.

In mathematics and computer science, an index often denotes a position or label for elements in a sequence, array, or set. Index variables (such as i or j) enumerate elements, and indexing is the operation of accessing a specific element by its position.

In economics, an index is a statistical measure that aggregates the performance of a selected set of assets, markets, or prices to reflect overall trends, such as stock market indices or price indices.

Overall, indekso denotes a broad family of concepts centered on organizing, referencing, and measuring information, with precise meaning varying by field and context.
