    Session: Querying: How to Work with Suggestions

    The suggestion feature is available through query extension methods. It gives you the ability to find word similarities using string distance algorithms.

    Syntax

    query.suggestUsing(suggestion);

query.suggestUsing(suggestionBuilder);
    Parameters
    suggestion SuggestionBase Defines the type of suggestion that should be executed
    suggestionBuilder (SuggestionBuilder) => void Builder with a fluent API that constructs a SuggestionBase instance

    Builder

    suggestionBuilder.byField(fieldName, term);

suggestionBuilder.byField(fieldName, terms);

suggestionBuilder.withOptions(options);
    Parameters
    fieldName string Points to the index field that should be used for operation
    term string Term that will be used as a basis of the suggestions
    terms string[] Terms that will be used as a basis of the suggestions
    options object Non-default options that should be used for operation
       pageSize number Maximum number of suggestions that will be returned
       distance StringDistanceTypes String distance algorithm to use (None, Levenshtein, JaroWinkler, NGram)
       accuracy number Suggestion accuracy
       sortMode SuggestionSortMode Indicates in what order the results should be returned (None, Popularity)

    Example I

    const suggestions = await session
    .query({ indexName: "Employees/ByFullName" })
    .suggestUsing(builder =>
        builder.byField("FullName", "johne")
            .withOptions({
                accuracy: 0.4,
                pageSize: 5,
                distance: "JaroWinkler",
                sortMode: "Popularity"
            }))
    .execute();
    from index 'Employees/ByFullName' 
select suggest('FullName', 'johne', '{ "Accuracy" : 0.4, "PageSize" : 5, "Distance" : "JaroWinkler", "SortMode" : "Popularity" }')

    Example II

    const suggestionWithTerm = new SuggestionWithTerm("fullName");
suggestionWithTerm.term = "johne";

const suggestions = await session
    .query({ indexName: "Employees/ByFullName" })
    .suggestUsing(suggestionWithTerm)
    .execute();
    from index 'Employees/ByFullName' 
select suggest('FullName', 'johne')
