Classes

• class CQueryNode

  CQueryNode is an abstract class for any node in a query parse tree. A parse tree is built by YACC during CQueryParser::ParseQuery. This class contains all members which are common to atomic and operation nodes. More...
  

• class CQueryBinaryOperationNode
• class CQueryAndOperation

  CQueryAndOperation implements the hit intersection or "and" operator: for example, "Mother&&father". More...
  

• class CQueryOrOperation

  CQueryAndOperation implements the hit union or "or" operator: for example, "Mother||father". More...
  

• class CQueryTokenNode

  CQueryTokenNode is a class which corresponds to one token or it's singular property (for example lemma). More...
  

• class CQuerySequenceNode

  CQuerySequenceNode is an implementation of sequence operator, for example, "Mother and father". This class holds a sequence of nodes of type CQueryTokenNode (slot m_Items). Between m_Items[i] and m_Items[i+1] must be no more than m_Distances[i] tokens. More...
  

• class CQueryNearNode

  CQueryNearNode is a class which is used to search two or three nodes, which are inside some text period of length CQueryNearNode::m_Distance. It other words it is an implementation of "near" operator: for example, NEAR(a,b,2). More...
  

• class CQueryWithNode

  CQueryWithNode is a class which is used to search a node which simultaneously has two properties, namely m_pChild1 and m_pChild2. (implementation of "with" operator: for example, Mother with [NOUN] ). More...
  

Functions

• void GetWordForms (const MorphLanguageEnum Langua, const string &src, set< string > &WordForms)

Function Documentation

void GetWordForms	(	const MorphLanguageEnum	Langua,
		const string &	src,
		set< string > &	WordForms
	)

compute the set of types WordForms which may share a lemma with src in language Langua.

The underlying CLemmatizer should handle transcoding of user queries transparently, assuming you called CLemmatizer::initIconv() with the appropriate encoding arguments.

This is very ugly, and the entire morphology system needs an overhaul.

Formerly a hidden function in QueryNode.cpp.
