info about private int processField(IndexableField field, long fieldGen, int fieldCount)

[Cristian Lorenzetto]

i m investigating about the update method for understanding if it is
possible update a single field , not only all document



 the code

 try {
      for (IndexableField field : docState.doc) {
        fieldCount = processField(field, fieldGen, fieldCount);
      }


seams to tell that is not so difficult to add a method *updateFieldDocument(Int
docid, IndexableField field) *

but maybe there is some thing i dont know sufficientely for my deduction.
