The Coveo Cloud V2 glossary defines Coveo Cloud related terms, expressions, abbreviations as well as concepts, products, components,  modules, or features.


The glossary, currently incomplete, is a work in progress.


An activity is an event related to a specific Coveo Cloud V2 platform concept such as a source, a field, an indexing pipeline extension, etc. (see Activity - Panel).

administration console

See Coveo Cloud V2 administration console

advanced query expression

The advanced query expression is a part of the larger query expression (the aq value) that is typically hidden to the end-user and  generated by code based on various rules such as facet selections. 


See advanced query expression.

basic query expression

The basic query expression is the part of the larger query expression (the q value) that typically comes from end user input, such as when a user is typing keywords in a search box.

constant query expression

The constant query expression is a part of the larger query expression (the cq value) similar to the advanced query expression, but that must hold expressions such as a search scope that are constant for all users of a specific search interface or search tab.  The results of evaluating those expressions are kept in a special index cache to avoid re-evaluating them on each query. 

Coveo Cloud query pipeline

Coveo Cloud query pipeline is a conditionally applied Search API set of query pipeline features that can be defined to modify a query (see What Is a Query Pipeline?). 

Coveo Cloud query syntax

The Coveo Cloud query syntax is the set of semantic rules that allows a user to compose an advanced query to send to the Search API (see Coveo Cloud Query Syntax Reference).

Coveo Cloud usage analytics

The Coveo Cloud usage analytics is a cloud service that records user interactions sent from Coveo search interfaces (and optionally page views from web) content allowing administrators to monitor Coveo solution usage (see Coveo Cloud Usage Analytics).

The usage analytics data also feeds Coveo Machine Learning models that are learning user behavior to suggest more relevant content. 

Coveo Cloud V2 administration console

The Coveo Cloud V2 administration console is a web application that allows an administrator to manage a Coveo Cloud V2 organization from a graphical user interface (see Coveo Cloud V2 Administration Console ).

The administration console relies on all of the REST API services exposed by the Coveo Cloud V2 platform

Coveo Cloud V2 indexing pipeline

The Coveo Cloud V2 Indexing Pipeline is the process through which each source item goes when it is indexed in a Coveo Cloud V2 organization (see Coveo Cloud V2 Indexing Pipeline). 

Coveo Cloud V2 organization

Coveo Cloud V2 organization is a single tenant instance hosting data and Coveo Cloud V2 platform service configurations allowing a company/corporation/organization to make multiple public and private enterprise content securely searchable with optimized relevance powered by Coveo Cloud usage analytics and Coveo Machine Learning (see  Organization - Section)

Coveo Cloud V2 platform


The Coveo Cloud V2 platform is an enterprise-class native cloud SaaS/PaaS solution that provides a unified and secure way to search for contextually relevant content across multiple enterprise systems (see  Coveo Cloud V2). The platform relies on Coveo Cloud usage analytics data to yield machine learning powered recommendations. The platform embraces the concepts of micro-services and scalability, allowing users to expand their search solution as their business grows.

Coveo JavaScript Search Framework

The Coveo JavaScript Search Framework is an open-source set of components (such as a search box, facets, a search result list, sort options) that you can assemble to easily build a feature-rich HTML search page getting results from a Coveo index (see JavaScript Search Framework Home). 

The Coveo JavaScript search page sends search requests to the Search API to get query results, and sends events to the Usage Analytics Write API to log Coveo Cloud usage analytics data. 

Coveo Machine Learning

Coveo Machine Learning is an artificial intelligence (AI) based cloud service hosting machine learning models used to provide more relevant content (see Coveo Machine Learning).

The models learn from Coveo Cloud usage analytics data and validate with the Coveo Cloud index that the querying user has the permission to view each recommended item.


See constant query expression.

disjunctive query expression

The disjunctive query expression is the part of the larger query expression (the dq value) that is merged with the other expression parts using an OR boolean operator. 


See disjunctive query expression.


See query pipeline feature.


A field is a Coveo Cloud V2 organization data container populated with a metadata value type (string, integer, float, or date/time) to provide specific information about an item while it passes through the Coveo Cloud V2 indexing pipeline stages (see Fields - Page). 


An index is a data struture allowing to quickly return items matching a specific query

Indexing Pipeline

See Coveo Cloud V2 indexing pipeline.

indexing pipeline extension

An indexing pipeline extension is a script defined in your Coveo Cloud V2 organization that can be applied to one or more sources to modify how items are indexed (see Coveo Cloud V2 Indexing Pipeline Extensions).  

An administrator can manage indexing pipeline extensions from the Coveo Cloud V2 administration console (see Extensions - Page). 


An item is a source index element (such as a document or an object) originally from an enterprise system that can be returned as a single search result.

query is a set of one or more expressions sent to a service such as an index to return matching relevant items

query function

A query function is a mathematical expression evaluated against each item returned by a query, and whose output is stored in a dynamic, temporary field generated at query time (see Query Function).

query pipeline

See Coveo Cloud query pipeline.

query pipeline feature

A query pipeline feature is a query pipeline statement expressing a meaningful action in the Coveo Cloud query pipeline, such as a Coveo Machine Learning model, a thesaurus rule, a featured result rule, a ranking weights rule, etc.

query pipeline language

The query pipeline language, also known as QPL (pronounced qupel) is a simple language to express the various query pipeline features supported by the Coveo Cloud query pipeline (see Query Pipeline Language (QPL)).

query pipeline statement

A query pipeline statement is an expression constructed using query pipeline language building blocks such as primitive types, lists, conditions, objects, etc.

ranking function

A ranking function is a mathematical expression evaluated against each item returned by a query, and whose output is added to the ranking score of the current item (see Ranking Function). 

Search UI

The name of the Coveo JavaScript Search Framework GitHub repository (see search-ui). 


A source is a Coveo Cloud V2 index container holding all items related to a specific enterprise system such as Google Drive, Web, or SharePoint (see Sources - Page).


See query pipeline statement.

usage analytics
