Class IndexConfiguration

java.lang.Object

lux.index.IndexConfiguration

public class IndexConfiguration
extends Object

Maintains a list of field definitions and index options that inform indexing and search. The configuration options and core indexing setup are immutable, but new fields may be added, fields may be renamed, and namespace mappings may be defined.

static FieldDefinition	ELEMENT_TEXT element text field indexes all the text along with element QNames.
static FieldDefinition	ELT_QNAME element QName field

Field Detail

LUCENE_VERSION

public static final org.apache.lucene.util.Version LUCENE_VERSION

BUILD_DOCUMENT

public static final int BUILD_DOCUMENT

causes a document node to be built during indexing. Must be set if any XPathFields are to be defined.

See Also:

Constant Field Values

SOLR

public static final int SOLR

Configure for use in solr; eg TinyBinarySolrField instead of TinyBinaryField

See Also:

Constant Field Values

NAMESPACE_AWARE

public static final int NAMESPACE_AWARE

causes QNames indexes to include the full namespace uri. If not set, QNames are indexed lexically, as {prefix}:{localname} without regard for any prefix mappings. Currently namespace-unaware indexing and search is not fully supported.

See Also:

Constant Field Values

STORE_DOCUMENT

public static final int STORE_DOCUMENT

causes a document to be stored in the index. This should generally always be enabled

See Also:

Constant Field Values

STORE_TINY_BINARY

public static final int STORE_TINY_BINARY

indicates that documents are to be stored in TinyBinary format. If this is not set, documents are stored as serialized XML.

See Also:

Constant Field Values

INDEX_QNAMES

public static final int INDEX_QNAMES

enables the ELT_QNAME and ATT_QNAME fields, causing element and attribute QNames to be indexed. If paths are indexed, this isn't really needed.

See Also:

Constant Field Values

INDEX_PATHS

public static final int INDEX_PATHS

enables the PATH field, causing element and attribute QName paths to be indexed.

See Also:

Constant Field Values

INDEX_FULLTEXT

public static final int INDEX_FULLTEXT

enables the XML_TEXT, ELEMENT_TEXT, and ATTRIBUTE_TEXT fields, causing element and attribute text to be indexed.

See Also:

Constant Field Values

INDEX_VALUES

public static final int INDEX_VALUES

enables the PATH_VALUE field (if INDEX_PATHS is set), and the QNAME_VALUE field (if INDEX_QNAMES is set), causing values to be indexed. This is an experimental feature that is not fully supported.

See Also:

Constant Field Values

COMPUTE_OFFSETS

public static final int COMPUTE_OFFSETS

enables the computation and storage of term offsets in the index. Currently there is no reason to enable this flag. In the future term offsets may be used to accelerate highlighting.

See Also:

Constant Field Values

STRIP_NAMESPACES

public static final int STRIP_NAMESPACES

causes all namespace information to be stripped from incoming documents

See Also:

Constant Field Values

INDEX_EACH_PATH

public static final int INDEX_EACH_PATH

experimental: index each occurrence of each path as an unparsed string, rather than indexing unique paths and tokenizing

See Also:

Constant Field Values

INDEXES

public static final int INDEXES

mask covering all of the indexing options

See Also:

Constant Field Values

DEFAULT_OPTIONS

public static final int DEFAULT_OPTIONS

the default indexing options

See Also:

Constant Field Values
