Hi Bernd,
the extraction result is created in CmsDocumentXmlContent
https://github.com/alkacon/opencms-core/blob/branch_7_5_x/src/org/opencms/search/documents/CmsDocumentXmlContent.java#L123
but my suggestion would be to map your date to a property. This is done
in the appinfo node of the schema of your XML content e.g.:
<mapping element="MyDate" mapto="property:myDate" />
Then, as you can see the method
String getStringValue(
CmsObject cms,
CmsResource res,
I_CmsExtractionResult extractionResult,
List<CmsProperty> properties,
List<CmsProperty> propertiesSearched) {
in CmsSearchFieldMapping - which you have already implemented - presents
you a List of properties ...
good luck
Rüdiger
