Constructor & Destructor Documentation

__construct

(

)

Object constructor.

Member Function Documentation

emptyNotOperatorAction

(

)

default (omitted) + NOT operator processing

Zend_Search_Lucene_Search_QueryParser

emptyOperatorAction

(

)

default (omitted) operator processing

Zend_Search_Lucene_Search_QueryParser

finishExpression

(

)

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

Returns

array

Exceptions

Zend_Search_Lucene_Exception

literalAction

(

)

Literal processing.

notOperatorAction

(

)

NOT operator processing.

orOperatorAction

(

)

OR operator processing Close current conjunction.

processLiteral

(

$literal

)

Process expression literal.

Parameters

integer

$operator

processOperator

(

$operator

)

Process next operator.

Operators are defined by class constants: IN_AND_OPERATOR, IN_OR_OPERATOR and IN_NOT_OPERATOR

Parameters

integer

$operator
