void emptyOperatorAction ()

array finishExpression ()

void notOperatorAction ()

void orOperatorAction ()

void processLiteral ( $literal, integer $operator)

Methods

emptyNotOperatorAction (line 233)

default (omitted) + NOT operator processing

access: public

void emptyNotOperatorAction ()

emptyOperatorAction (line 215)

default (omitted) operator processing

access: public

void emptyOperatorAction ()

finishExpression (line 194)

Finish an expression and return result

Result is a set of boolean query conjunctions

Each conjunction is an array of conjunction elements Each conjunction element is presented with two-elements array: array(<literal>, <is_negative>)

So, it has a structure: array( array( array(<literal>, <is_negative>), // first literal of first conjuction array(<literal>, <is_negative>), // second literal of first conjuction ... array(<literal>, <is_negative>) ), // end of first conjuction array( array(<literal>, <is_negative>), // first literal of second conjuction array(<literal>, <is_negative>), // second literal of second conjuction ... array(<literal>, <is_negative>) ), // end of second conjuction ... ) // end of structure

throws: Zend_Search_Lucene_Exception
