SearchSuggestionSpec

const val SUGGESTION_RANKING_STRATEGY_DOCUMENT_COUNT = 0: Int

Ranked by the document count that contains the term.

Suppose the following document is in the index.

Doc1 contains: term1 term2 term2 term2

Doc2 contains: term1

Then, suppose that a search suggestion for "t" is issued with the DOCUMENT_COUNT, the returned SearchSuggestionResults will be: term1, term2. The term1 will have higher score and appear in the results first.

const val SUGGESTION_RANKING_STRATEGY_NONE = 2: Int

No Ranking, results are returned in arbitrary order.

const val SUGGESTION_RANKING_STRATEGY_TERM_FREQUENCY = 1: Int

Ranked by the term appear frequency.

Suppose the following document is in the index.

Doc1 contains: term1 term2 term2 term2

Doc2 contains: term1

Then, suppose that a search suggestion for "t" is issued with the TERM_FREQUENCY, the returned SearchSuggestionResults will be: term2, term1. The term2 will have higher score and appear in the results first.

fun getFilterDocumentIds(): (Mutable)Map<String!, (Mutable)List<String!>!>

Returns the map of namespace and target document ids to search over.

The keys of the returned map are namespaces, and the values are the target document ids in that namespace to search over.

If addFilterDocumentIds was never called, returns an empty map. In this case AppSearch will search over all namespace and document ids.

Calling this function repeatedly is inefficient. Prefer to retain the Map returned by this function, rather than calling it multiple times.

fun getFilterNamespaces(): (Mutable)List<String!>

Returns the list of namespaces to search over.

If empty, will search over all namespaces.

fun getFilterSchemas(): (Mutable)List<String!>

Returns the list of schema to search the suggestion over.

If empty, will search over all schemas.

fun getMaximumResultCount(): Int

Returns the maximum number of wanted suggestion that will be returned in the result object.

fun getRankingStrategy(): Int

Returns the ranking strategy.
