Searching with Coveo Cloud

Coveo Cloud provides intelligent search, delivering the most relevant results possible from a potentially large amount of data. You can leverage the power of Coveo Cloud through a good use of all the tools and search features.

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 are 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 Cloud.

Coveo Cloud 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 is expanded with at least:

  • Words sharing the same stem as your keywords.

    You type in the following query:

    The query that is executed is:

    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 Managing Query Pipeline Thesaurus).

    The administrator noticed in the analytics 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:

    The query that is actually sent is:

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

Security being a key feature in Coveo Cloud, the engine also checks the permissions model for each item relevant to your search and only returns items you are allowed to access (see Coveo Cloud V2 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, Coveo Cloud Query Syntax Reference, and Advanced Field Queries).

Query Only returns
items containing these exact keywords in the same order. [more]

You can also leverage wildcard characters in advanced field queries (see Advanced Field Queries). If you have querying issues, see Troubleshooting Querying Issues for troubleshooting guidelines.
