Detailed Description
This is used in the Model/View Programming paradigm to display a list of search results, to highlight them on the rendered PDF pages, and to iterate through them using the "search forward" / "search backward" buttons and shortcuts that would be found in a typical document-viewing UI:

QPdfSearchModel::QPdfSearchModel(QObject *parent)
Constructs a new search model with parent object parent.
[override virtual noexcept]
QPdfSearchModel::~QPdfSearchModel()
Destroys the model.
[override virtual]
QVariant QPdfSearchModel::data(const QModelIndex &index, int role) const
Reimplements: QAbstractItemModel::data(const QModelIndex &index, int role) const.
QPdfLink QPdfSearchModel::resultAtIndex(int index) const
Returns a result found by index in the document, regardless of the page on which it was found. index must be less than rowCount.
QList<QPdfLink> QPdfSearchModel::resultsOnPage(int page) const
Returns the list of all results found on the given page.
[override virtual]
QHash<int, QByteArray> QPdfSearchModel::roleNames() const

[override virtual]
int QPdfSearchModel::rowCount(const QModelIndex &parent) const
Reimplements: QAbstractItemModel::rowCount(const QModelIndex &parent) const.
The number of rows in the model is equal to the number of search results found.
