All Implemented Interfaces:

public class WordExtractor
extends java.lang.Object
implements com.atlassian.bonnie.search.Extractor

Extractor responsible for adding tokenized field used by the "Did You Mean" feature to rank suggestions. Ranking is done by checking the frequency of a dictionary suggestion against the contents of this field. The more often it occurs, the higher the frequency. Frequency checking cannot be done on "contentBody" field because the tokenization on this field does not lowercase terms and breaks them down into word stems - stemmed tokens with their case intact are un-useable for this feature.
