: Q1. Is is possible to pass *analyzed* content to the : : public abstract class Signature {
No, analysis happens as the documents are being written to the lucene index, well after the UpdateProcessors have had a chance to interact with the values. : Q2. Method calculate() is using concatenated fields from <str : name="fields">name,features,cat</str> : Is there any mechanism I could build "field dependant signatures"? At the moment the Signature API is fairly minimal, but it could definitley be improved by adding more methods (that have sensible defaults in the base class) that would give the impl more control over teh resulting signature ... we just beed people to propose good suggestions with example use cases. : Is idea to make two UpdadeProcessors and chain them OK? (Is ugly, but : would work) I don't know that what you describe is really intentional or not, but it should work -Hoss
