mixed $_coord = 'null'
A score factor based on the fraction of all query subqueries that a document contains.
float for conjunction queries array of float for non conjunction queries
array $_resVector = 'null'
Result vector.
array $_signs = 'array'
Subqueries signs.
If true then subquery is required. If false then subquery is prohibited. If null then subquery is neither prohibited, nor required
If array is null then all subqueries are required
array $_subqueries = 'array'
Subqueries Array of Zend_Search_Lucene_Search_Query
__construct(
array $subqueries
=
null, array $signs
=
null
)
:
void
Class constructor. Create a new Boolean query object.
if $signs array is omitted then all subqueries are required it differs from addSubquery() behavior, but should never be used
__toString(
)
:
string
Print a query
_calculateConjunctionResult(
)
:
Calculate result vector for Conjunction query (like '<subquery1> AND <subquery2> AND <subquery3>')
_calculateNonConjunctionResult(
)
:
Calculate result vector for non Conjunction query (like '<subquery1> AND <subquery2> AND NOT <subquery3> OR <subquery4>')
_conjunctionScore(
integer $docId, Zend_Search_Lucene_Interface $reader
)
:
float
Score calculator for conjunction queries (all subqueries are required)
_highlightMatches(
Zend_Search_Lucene_Search_Highlighter_Interface $highlighter
)
:
Query specific matches highlighting
_nonConjunctionScore(
integer $docId, Zend_Search_Lucene_Interface $reader
)
:
float
Score calculator for non conjunction queries (not all subqueries are required)
addSubquery(
Zend_Search_Lucene_Search_Query $subquery, boolean|null $sign
=
null
)
:
void
Add a $subquery (Zend_Search_Lucene_Search_Query) to this query.
The sign is specified as: TRUE - subquery is required FALSE - subquery is prohibited NULL - subquery is neither prohibited, nor required
createWeight(
Zend_Search_Lucene_Interface $reader
)
:
Zend_Search_Lucene_Search_Weight
Constructs an appropriate Weight implementation for this query.
execute(
Zend_Search_Lucene_Interface $reader, Zend_Search_Lucene_Index_DocsFilter|null $docsFilter
=
null
)
:
Execute query in context of index reader It also initializes necessary internal structures
getQueryTerms(
)
:
array
Return query terms
getSigns(
)
:
array
Return subqueries signs
getSubqueries(
)
:
array
Returns subqueries
matchedDocs(
)
:
array
Get document ids likely matching the query
It's an array with document ids as keys (performance considerations)
optimize(
Zend_Search_Lucene_Interface $index
)
:
Zend_Search_Lucene_Search_Query
Optimize query in the context of specified index
rewrite(
Zend_Search_Lucene_Interface $index
)
:
Zend_Search_Lucene_Search_Query
Re-write queries into primitive queries
score(
integer $docId, Zend_Search_Lucene_Interface $reader
)
:
float
Score specified document
