You can tell Strigi what information to retrieve by stating the names of the 
fields from the ontologies you would like in AnalyzerConfiguration. A mapping 
from KFileMetaInfo::What to collections of these field names is possible.

There is currently no generic way to know how much of a file must be read to 
retrieve the value of a particular field.
