Constants
SUGGESTION_RANKING_STRATEGY_DOCUMENT_COUNT
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 SearchSuggestionResult
s will be: term1, term2. The term1 will have higher
score and appear in the results first.
Constant Value: 0 (0x00000000)
SUGGESTION_RANKING_STRATEGY_NONE
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
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 SearchSuggestionResult
s will be: term2, term1. The term2 will have higher
score and appear in the results first.
Constant Value: 1 (0x00000001)
Fields
Public methods
getFilterDocumentIds
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
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
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
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
public int getMaximumResultCount ()
Returns the maximum number of wanted suggestion that will be returned in the result object.
Returns | |
---|---|
int |
getRankingStrategy
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 |
writeToParcel
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 |
