Method Details

getDocument

public org.apache.lucene.document.Document getDocument()

getId

public String getId()

Specified by:

getId in interface SearchDocument

getResource

public String getResource()

Specified by:

getResource in interface SearchDocument

getContext

public String getContext()

Specified by:

getContext in interface SearchDocument

getPropertyNames

public Set<String> getPropertyNames()

Description copied from interface: SearchDocument

Returns a set of the property names.

Specified by:

getPropertyNames in interface SearchDocument

addProperty

public void addProperty(String name)

Description copied from interface: SearchDocument

Adds/creates a new property with the given name.

Specified by:

addProperty in interface SearchDocument

addProperty

public void addProperty(String name,
 String text)

Stores and indexes a property in a Document. We don't have to recalculate the concatenated text: just add another TEXT field and Lucene will take care of this. Additional advantage: Lucene may be able to handle the invididual strings in a way that may affect e.g. phrase and proximity searches (concatenation basically means loss of information). NOTE: The TEXT_FIELD_NAME has to be stored, see in LuceneSail
