Yes, kind of. Basically all you need to get an application to show a
textdocument, be able to search it, and show page thumbs, all you gotta do
is this-

import QtQuick 1.1
import org.calligra.CalligraComponents 0.1 as Calligra

Item {
    width: 100
    height: 200

    Calligra.TextDocumentCanvas {
        id: canvas
        source: "document.odt"
        anchors.fill: parent
        zoomMode: Calligra.TextDocumentCanvas.ZOOM_WIDTH

        MouseArea {
            anchors.fill: parent
            onClicked: parent.searchTerm = 'text'
        }

        ListView {
            id: pageThumbnails
            anchors.centerIn: parent
            model: canvas.documentModel
            delegate: Image { source: decoration }
        }
    }
}

Sweet, isn't it? :D

I'll take that as a +1, anyone else having different views? We need to be
sure before we do such a refactoring ;)
