More Advanced Search

The Coveo Platform offers several methods to perform more precise or more sophisticated searches. In the search box, you can use a variety of expressions to find exactly what you are looking for.

Example: You can use the following query to find all documents containing specifics terms that are nearby in a document that was created or modified at least a month ago.

Normal keywords – both must be present in the found documents.
Field query – the documents must be created or modified at least a month ago.
Proximity operator – The terms must be present ten or less terms apart in the found documents

Prefixes and Operators

The Coveo Platform supports a number of prefixes and various types of operators (Boolean, mathematical, date, email,…) to help you create more precise queries (see Search Prefixes and Operators and Using Special Characters in Queries).

Field Codes

In the Coveo unified index, a field contains information from metadata that comes with the indexed documents. Metadata is information about a document rather than information contained in a document (see What Are Field Queries and Free Text Queries?). The Coveo Platform supports numerous field codes for a variety of systems (see Available Field Aliases). You can use field queries (see Useful Field Query Examples).


By default you can use wildcard characters (? and *) in a query to expand keywords and therefore expand the query (see Using Wildcards in Queries).

Query String Parameters

The URL of the search interface can include a number of query string parameters to more precisely control the query sent to the server (see .NET Search Query String Parameters).

Tip: You probably already use complex queries without knowing (see User Interface Elements Hiding Complex Queries).
