A synonym set is defined with a master expression and a set of associated expressions (an expression is defined by many words with a space as separator) originalExpr = {alternativeExpr1, ...., alternativeExprN}.When query is parsed we expand originalExpr with {alternativeExpr1, ..., alternativeExprN}. When equivalenceClass Boolean is set to true, we also expand: - alternativeExpr1 by originalExpr, alternativeExpr2, ..., alternativeExprN - alternativeExpr2 by originalExpr, alternativeExpr1, alternativeExpr3, ..., alternativeExprN - ... - alternativeExprN by originalExpr, alternativeExpr1, ..., alternativeExprN-1

If false, synonym matching is punctuation-insensitive.

Path to the compiled ontology containing stopwords used at build time when generating permutations.

If true, adds for each synonym some extra forms made of words permutations after removing stopwords.

If true, adds for each synonym an extra form from which stopwords have been removed.
