Searching with Coveo

In this article

Coveo provides intelligent search, delivering the most relevant results possible from a potentially large amount of data. You can leverage the power of Coveo through a good use of all the tools and search features (see Get Started With Coveo-Powered Search Pages).

Your typical entry point is the search box, where you can enter a query relevant to the items you want to retrieve from the index. You must enter a query precise enough to find only the items you’re looking for, but not so precise that it leaves out items that may be useful to you. The documentation in this section covers the search operations a user can execute with Coveo.

Coveo provides an intelligent engine to delve into the Coveo unified index, which contains all the items you may need. The engine looks in the unified index for the keywords you type in the search box to find items containing these keywords.

When you send your query, it’s expanded with at least:

  • Words sharing the same stem as your keywords.

    You type in the following query:


    The query that’s executed is:

    performance OR perform OR performances OR performed OR performer OR performing OR performs

    You get in your search results all items containing at least one occurrence of performance, perform, performances, performed, performer, performing, or performs.

  • Synonyms of your keywords, if your system administrator defined any in the thesaurus (see Manage thesaurus rules).

    The administrator noticed in the usage analytics data that people were looking for joker but your item uses the term wildcard. The administrator has then set the word joker as a synonym of wildcard. You enter the following query:

    using joker in Coveo

    The query that’s actually sent is:

    using joker OR wildcard in Coveo

    Your search results are items that contain either joker or wildcard along with your other keywords.

Security being a key feature in the Coveo Platform, the engine also checks the permission model for each item relevant to your search and only returns items you’re allowed to access (see Coveo management of security identities and item permissions).


You can also use several search operators and prefixes in the search box to either precise or broaden the search scope (see Search Prefixes and Operators, Query syntax, and Advanced Field Queries).
