LuceneOptionsImpl

public LuceneOptionsImpl(DocumentFieldMetadata fieldMetadata,
                 float fieldLevelBoost,
                 float documentLevelBoost)

Method Detail

addFieldToDocument

public void addFieldToDocument(String name,
                      String indexedString,
                      Document document)

Description copied from interface: LuceneOptions

Add a new field with the name fieldName to the Lucene Document document using the value indexedString. If the indexedString is null then the field is not added to the document. The field options are following the user declaration:

• stored or not
• compressed or not
• what type of indexing strategy
• what type of term vector strategy

Specified by:

addFieldToDocument in interface LuceneOptions

Parameters:

name - The field name

indexedString - The value to index

document - the document to which to add the the new field

getBoost

public float getBoost()

Description copied from interface: LuceneOptions

Prefer the use of LuceneOptions.addFieldToDocument(String, String, org.apache.lucene.document.Document) over manually building your Field objects and adding them to the Document.

Specified by:

getBoost in interface LuceneOptions

Returns:

Returns the boost factor declared by the user

indexNullAs

public String indexNullAs()

Specified by:

indexNullAs in interface LuceneOptions

Returns:

Returns the string for indexing null values. null is returned in case no null token has been specified.

isCompressed

public boolean isCompressed()

Description copied from interface: LuceneOptions

Prefer the use of LuceneOptions.addFieldToDocument(String, String, org.apache.lucene.document.Document) over manually building your Field objects and adding them to the Document. To use compression either use #addFieldToDocument or refer to Lucene documentation to implement your own compression strategy.

Specified by:

isCompressed in interface LuceneOptions

Returns:

the compression strategy declared by the user true if the field value is compressed, false otherwise.

getIndex

public Field.Index getIndex()

Description copied from interface: LuceneOptions

Prefer the use of LuceneOptions.addFieldToDocument(String, String, org.apache.lucene.document.Document) over manually building your Field objects and adding them to the Document.

Specified by:

getIndex in interface LuceneOptions

Returns:

Returns the indexing strategy declared by the user

getStore

public Field.Store getStore()

Description copied from interface: LuceneOptions

Prefer the use of LuceneOptions.addFieldToDocument(String, String, org.apache.lucene.document.Document) over manually building your Field objects and adding them to the Document. org.apache.lucene.document.Field.Store.YES if the field is stored org.apache.lucene.document.Field.Store.NO otherwise. To determine if the field must be compressed, use LuceneOptions.isCompressed(). Starting from version 3.3, Store.COMPRESS is no longer returned, use LuceneOptions.isCompressed() To use compression either use #addFieldToDocument or refer to Lucene documentation to implement your own compression strategy.

Specified by:

getStore in interface LuceneOptions

Returns:

Returns the store strategy declared by the user

getTermVector

public Field.TermVector getTermVector()

Description copied from interface: LuceneOptions

Prefer the use of LuceneOptions.addFieldToDocument(String, String, org.apache.lucene.document.Document) over manually building your Field objects and adding them to the Document.

Specified by:

getTermVector in interface LuceneOptions

Returns:

Returns the term vector strategy declared by the user
