About Query Suggestions (QS)

The Coveo Machine Learning Query Suggestions (QS) feature recommends relevant queries to users as they type in the search box.


Coveo ML QS models:

  • Identify exact, partial, or fuzzy matches with typed characters anywhere in any individual keyword appearing in any order.

  • Stem query suggestion keywords to remove duplicates.

  • Offer the most relevant recommendations by ranking query suggestions by considering the following:

    • The number of times the query was performed.

    • The degree to which the query suggestion matches the typed characters.

    • The query performance based on the Relevance Index and Click-Through usage analytics metrics.

  • Only consider queries that were followed by clicked search results a specific number of times (see Reviewing Coveo Machine Learning Query Suggestion Candidates). This prevents infrequent queries from polluting the suggestions.
