Class LeafOptionsParser

java.lang.Object

com.exalead.search.query.node.NodeVisitor

com.exalead.search.query.util.LeafOptionsParser

public class LeafOptionsParser
extends NodeVisitor

Parse raw options on tree leaves. Supported options are: e/exact : Set matching to exact i/lowercase : Set matching to lowercase_only n/normalized: Set matching to normalized_only e_i: Set matching to exact/lowercase e_n: Set matching to exact/lowercase/normalized i_n: Set matching to lowercase/normalized k=[0,1,2] : Set matching to exact/lowercase/normalized patternMatches=[int] : Set maximum number of matches (pattern expansions) key=value: custom key/value This processor can override some options defined by the distribution of linguistic expansions. It should therefore come after the LinguisticExpansionsConfigurator Regexp-specific options: #= Set maximum number of matches
