/** Advanced search history.

* We store previous searches using the "dynconf" mechanism, as string
* entries under the "advSearchHist" key. The strings are generated by
* translating the SearchData structure to XML, which is done by
* calling SearchData::asXML().
* When reading, we use a QXmlSimpleReader and QXmlDefaultHandler to
* turn the XML back into a SearchData object, which is then passed to
* the advanced search object fromSearch() method to rebuild the
* window state.
*
* XML generation is performed by ../rcldb/searchdataxml.cpp.
* See xmltosd.h for a schema description
