    \ingroup QtLocation-places
    \ingroup QtLocation-places-requests
    \since 5.6

    \brief The QPlaceSearchRequest class represents the set of parameters for a search request.

    A typical search request may look like the following:
    \snippet places/requesthandler.h Search request

    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.

/*!
    \enum QPlaceSearchRequest::RelevanceHint

    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.
