Returns the number of documents in this index containing the $term.
Name | Type | Description |
---|---|---|
$term | \Zend_Search_Lucene_Index_Term |
Type | Description |
---|---|
integer |


find(mixed $query) : array
Performs a query against the index and returns an array of Zend_Search_Lucene_Search_QueryHit objects.
Input is a string or Zend_Search_Lucene_Search_Query.
Name | Type | Description |
---|---|---|
$query | mixed |
Type | Description |
---|---|
array | Zend_Search_Lucene_Search_QueryHit |
Exception | Description |
---|---|
\Zend_Search_Lucene_Exception |

Get current generation number
Returns generation number 0 means pre-2.1 index format -1 means there are no segments files.
Name | Type | Description |
---|---|---|
$directory | \Zend_Search_Lucene_Storage_Directory |
Type | Description |
---|---|
integer |
Exception | Description |
---|---|
\Zend_Search_Lucene_Exception |


getDefaultSearchField() : string
Get default search field.
Null means, that search is performed through all fields by default
Type | Description |
---|---|
string |


getDirectory() : \Zend_Search_Lucene_Storage_Directory
Returns the Zend_Search_Lucene_Storage_Directory instance for this index.
Type | Description |
---|---|
\Zend_Search_Lucene_Storage_Directory |


getDocument(integer | \Zend_Search_Lucene_Search_QueryHit $id) : \Zend_Search_Lucene_Document
Returns a Zend_Search_Lucene_Document object for the document number $id in this index.

getFieldNames(boolean $indexed = false) : array
Returns a list of all unique field names that exist in this index.
Name | Type | Description |
---|---|---|

Type | Description |
---|---|
array |


getMaxBufferedDocs() : integer
Retrieve index maxBufferedDocs option
maxBufferedDocs is a minimal number of documents required before the buffered in-memory documents are written into a new Segment
Default value is 10
Type | Description |
---|---|
integer |


getMaxMergeDocs() : integer
Retrieve index maxMergeDocs option
maxMergeDocs is a largest number of documents ever merged by addDocument(). Small values (e.g., less than 10,000) are best for interactive indexing, as this limits the length of pauses while indexing to a few seconds. Larger values are best for batched indexing and speedier searches.
Default value is PHP_INT_MAX
Type | Description |
---|---|
integer |


getMergeFactor() : integer
Retrieve index mergeFactor option
mergeFactor determines how often segment indices are merged by addDocument(). With smaller values, less RAM is used while indexing, and searches on unoptimized indices are faster, but indexing speed is slower. With larger values, more RAM is used during indexing, and while searches on unoptimized indices are slower, indexing is faster. Thus larger values (> 10) are best for batch index creation, and smaller values (< 10) for indices that are interactively maintained.
Default value is 10

---|---|
integer |
