ALL_PARAMS

public static final java.lang.String[] ALL_PARAMS

maxMatches

public int maxMatches

Maximum number of approximate matches. /!\ The actual default limit used by index-side approximate is in QueryExpansionConfigAST

relativeWeightDistance1

public double relativeWeightDistance1

Multiplicative factor on the weight of the expansions at edit distance 1

minCharsDistance1

public int minCharsDistance1

Minimum number of chars to search for edit distance <= 1

relativeWeightDistance2

public double relativeWeightDistance2

Multiplicative factor on the weight of the expansions at Levensteihn distance 2

minCharsDistance2

public int minCharsDistance2

Minimum number of chars to search for edit distance <= 2

malusOnFirstLetter

public boolean malusOnFirstLetter

Apply a malus in approximate algorithm if the first letter of matched word is not the same than first letter of original word. In that case, the computed edit distance is incremented
