\inmodule QtLocation
The QPlaceSearchRequest class represents the set of parameters for a search request.
A typical search request may look like the following:
Note that specifying a search center can be done by setting a circular search area that has a center but no radius. The default radius is set to -1, which indicates an undefined radius. The provider will interpret this as being free to choose its own default radius.
The QPlaceSearchRequest is primarily used with the QPlaceManager to \l {QPlaceManager::search()} {search for places}, however it is also used to provide parameters for \l {QPlaceManager::searchSuggestions()}{generating search term suggestions}. Note that in this context only some of the parameters may be relevant. For example, the search area is useful in narrowing down relevant search suggestions, while other parameters such as relevance hint are not so applicable.
Also be aware that providers may vary by which parameters they support for example some providers may not support paging while others do, some providers may honor relevance hints while others may completely ignore them, see the \l {Qt Location#Plugin References and Parameters}{plugin documentation} for more details.
Definition at line 18 of file qplacesearchrequest.h.
Defines hints to help rank place results.
\value UnspecifiedHint No explicit hint has been specified. \value DistanceHint Distance to a search center is relevant for the user. Closer places are more highly weighted. This hint is only useful if a circular search area is used in the query. \value LexicalPlaceNameHint Alphabetic ordering of places according to name is relevant to the user.

QPlaceSearchRequest::QPlaceSearchRequest | ( | ) |
Default constructor.
Constructs an new request object.
Definition at line 104 of file qplacesearchrequest.cpp.
|
defaultnoexcept |
Constructs a copy of other.
|
defaultnoexcept |
|
default |
Destroys the request object.
QList< QPlaceCategory > QPlaceSearchRequest::categories | ( | ) | const |
Return the categories to be used in the search request.
Places need only to belong to one of the categories to be considered a match by the request.
Definition at line 173 of file qplacesearchrequest.cpp.
void QPlaceSearchRequest::clear | ( | ) |
Clears the search request.
Definition at line 341 of file qplacesearchrequest.cpp.
int QPlaceSearchRequest::limit | ( | ) | const |
Returns the maximum number of search results to retrieve.
A negative value for limit means that it is undefined. It is left up to the backend provider to choose an appropriate number of results to return. The default limit is -1.
Definition at line 323 of file qplacesearchrequest.cpp.
|
noexcept |
Assigns other to this search request and returns a reference to this search request.
Definition at line 123 of file qplacesearchrequest.cpp.
QString QPlaceSearchRequest::recommendationId | ( | ) | const |
Returns the place id which will be used to search for recommendations for similar places.
Definition at line 229 of file qplacesearchrequest.cpp.
QPlaceSearchRequest::RelevanceHint QPlaceSearchRequest::relevanceHint | ( | ) | const |
Returns the relevance hint of the request.
The hint is given to the provider to help but not dictate the ranking of results. For example providing a distance hint may give closer places a higher ranking but it doesn't necessarily mean that he results will be ordered strictly according to distance.
Definition at line 302 of file qplacesearchrequest.cpp.
QGeoShape QPlaceSearchRequest::searchArea | ( | ) | const |
Returns the search area which will be used to limit search results.
The default search area is an invalid QGeoShape, indicating that no specific search area is defined.
Definition at line 210 of file qplacesearchrequest.cpp.
QVariant QPlaceSearchRequest::searchContext | ( | ) | const |
Returns backend specific additional search context associated with this place search request.
The search context is typically set as part of a \l {QPlaceSearchResult::ProposedSearchResult}{proposed search results}.
Definition at line 249 of file qplacesearchrequest.cpp.
QString QPlaceSearchRequest::searchTerm | ( | ) | const |
Returns the search term.
Definition at line 153 of file qplacesearchrequest.cpp.
void QPlaceSearchRequest::setCategories | ( | const QList< QPlaceCategory > & | categories | ) |
Sets the search request to search from the list of given categories.
Any places returned during the search will match at least one of the categories.
Definition at line 200 of file qplacesearchrequest.cpp.
void QPlaceSearchRequest::setCategory | ( | const QPlaceCategory & | category | ) |
Sets the search request to search by a single category.
Definition at line 184 of file qplacesearchrequest.cpp.
void QPlaceSearchRequest::setLimit | ( | int | limit | ) |
Set the maximum number of search results to retrieve to limit.
Definition at line 332 of file qplacesearchrequest.cpp.
Sets the placeId which will be used to search for recommendations.
Definition at line 238 of file qplacesearchrequest.cpp.
void QPlaceSearchRequest::setRelevanceHint | ( | QPlaceSearchRequest::RelevanceHint | hint | ) |
Sets the relevance hint to be used when searching for a place.
Definition at line 311 of file qplacesearchrequest.cpp.
Sets the search request to search within the given area.
Definition at line 219 of file qplacesearchrequest.cpp.
Sets the search context to context.
The search context is used by backends to store additional search context related to the search request. Other relevant fields should also be filled in. For example, if the search context encodes a text search the search term should also be set with \l setSearchTerm(). The search context allows additional search context to be kept which is not directly accessible via the Qt Location API.
The search context can be of any type storable in a QVariant. The value of the search context is not intended to be use directly by applications.
Definition at line 270 of file qplacesearchrequest.cpp.
Sets the search term.
Definition at line 162 of file qplacesearchrequest.cpp.
void QPlaceSearchRequest::setVisibilityScope | ( | QLocation::VisibilityScope | visibilityScopes | ) |
Sets the visibility scope used when searching for places.

Definition at line 35 of file qplacesearchrequest.h.
QLocation::VisibilityScope QPlaceSearchRequest::visibilityScope | ( | ) | const |
Returns the visibility scope used when searching for places.
The default value is QLocation::UnspecifiedVisibility meaning that no explicit scope has been assigned. Places of any scope may be returned during the search.
