Nested classes
`class`	`SearchSuggestionSpec.Builder` Builder for `objects`.

          java.lang.Object

`Object`	`clone()` Creates and returns a copy of this object.
`boolean`	`equals(Object obj)` Indicates whether some other object is "equal to" this one.

`final Class<?>`	`getClass()` Returns the runtime class of this `Object`.
`int`	`hashCode()` Returns a hash code value for the object.
`final void`	`notify()` Wakes up a single thread that is waiting on this object's monitor.
`final void`	`notifyAll()` Wakes up all threads that are waiting on this object's monitor.
`String`	`toString()` Returns a string representation of the object.
`final void`	`wait(long timeoutMillis, int nanos)` Causes the current thread to wait until it is awakened, typically by being notified or interrupted, or until a certain amount of real time has elapsed.
`final void`	`wait(long timeoutMillis)` Causes the current thread to wait until it is awakened, typically by being notified or interrupted, or until a certain amount of real time has elapsed.
`final void`	`wait()` Causes the current thread to wait until it is awakened, typically by being notified or interrupted.

From interface


        
          android.os.Parcelable

`abstract int`	`describeContents()` Describe the kinds of special objects contained in this Parcelable instance's marshaled representation.

Constants

SUGGESTION_RANKING_STRATEGY_DOCUMENT_COUNT

Added in API level 34
Also in T Extensions 7

public static final int SUGGESTION_RANKING_STRATEGY_DOCUMENT_COUNT

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.

Constant Value: 0 (0x00000000)

SUGGESTION_RANKING_STRATEGY_NONE

Added in API level 34
Also in T Extensions 7

public static final int SUGGESTION_RANKING_STRATEGY_NONE

No Ranking, results are returned in arbitrary order.

Constant Value: 2 (0x00000002)

SUGGESTION_RANKING_STRATEGY_TERM_FREQUENCY

Added in API level 34
Also in T Extensions 7

public static final int SUGGESTION_RANKING_STRATEGY_TERM_FREQUENCY

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.

Constant Value: 1 (0x00000001)

public static final Creator<SearchSuggestionSpec> CREATOR

Public methods

getFilterDocumentIds

Added in API level 34
Also in T Extensions 7

public Map<String, List<String>> getFilterDocumentIds ()

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 Builder.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.

Returns
`Map<String, List<String>>`	This value cannot be `null`.

getFilterNamespaces

Added in API level 34
Also in T Extensions 7

public List<String> getFilterNamespaces ()

Returns the list of namespaces to search over.

If empty, will search over all namespaces.

Returns
`List<String>`	This value cannot be `null`.

getFilterProperties

Added in API level 35
Also in T Extensions 13

public Map<String, List<String>> getFilterProperties ()

Returns the map of schema and target properties to search over.

The keys of the returned map are schema types, and the values are the target property path in that schema to search over.

If Builder.addFilterPropertyPaths was never called, returns an empty map. In this case AppSearch will search over all schemas and properties.

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

Returns
`Map<String, List<String>>`	This value cannot be `null`.

getFilterSchemas

Added in API level 34
Also in T Extensions 7

public List<String> getFilterSchemas ()

Returns the list of schema to search the suggestion over.

If empty, will search over all schemas.

Returns
`List<String>`	This value cannot be `null`.

getMaximumResultCount

Added in API level 34
Also in T Extensions 7

public int getMaximumResultCount ()

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

Returns
`int`

getRankingStrategy

Added in API level 34
Also in T Extensions 7

public int getRankingStrategy ()

Returns the ranking strategy.

Returns
`int`	Value is `SUGGESTION_RANKING_STRATEGY_NONE`, `SUGGESTION_RANKING_STRATEGY_DOCUMENT_COUNT`, or `SUGGESTION_RANKING_STRATEGY_TERM_FREQUENCY`

getSearchStringParameters

Added in Android Baklava

public List<String> getSearchStringParameters ()

Returns the list of String parameters that can be referenced in the query through the "getSearchStringParameter({index})" function.

Returns
`List<String>`	This value cannot be `null`.

See also:

AppSearchSession.search(String, SearchSpec)

writeToParcel

Added in API level 34

public void writeToParcel (Parcel dest, 
                int flags)

Flatten this object in to a Parcel.

Parameters
`dest`	`Parcel`: This value cannot be `null`.
`flags`	`int`: Additional flags about how the object should be written. May be 0 or `Parcelable.PARCELABLE_WRITE_RETURN_VALUE`. Value is either `0` or a combination of `Parcelable.PARCELABLE_WRITE_RETURN_VALUE`, and android.os.Parcelable.PARCELABLE_ELIDE_DUPLICATES
