Class AllAnalyzer

      org.compass.core.lucene.engine.all.AllAnalyzer

public class AllAnalyzer
extends Analyzer

The All Analyzer is a specific analyzer that is used to wrap the analyzer passed when adding a document. It will gather all the tokens that the actual analyzer generates for fields that are included in All and allow to get them using createAllTokenStream() (which will be used to create the all field with).

Un tokenized fields (which will not go through the analysis process) are identied when this analyzed is constructed and are added to the all field if they are supposed to be included. There are two options with the untokenized fields, either add them as is (un tokenized), or analyze them just for the all properties.
