Class SpellingSuggestionChooser

java.lang.Object
  no.sesat.search.result.handler.SpellingSuggestionChooser

All Implemented Interfaces:

ResultHandler

public final class SpellingSuggestionChooser
extends Object
implements ResultHandler

Spelling suggestions are chosen in the following way:

• Discard all suggestions with score less than minimumScore
• For each term, remove suggestions with lowest score so that the number of suggestions is less than maxSuggestions. If the query is long the limit is maxSuggestionsForLongQueries
• Remove all suggestions whose score differs more than maxDistance from the suggestion with the highest score
• If the query is long and if two terms have suggestions, remove all suggestions unless the best suggestion is much better than the second best

A new query is then created using the chosen suggestions.
