IndexableField |
createField(SchemaField field,
Object value,
float boost)
Used for adding a document when a field needs to be created from a type and a string. |
List<IndexableField> |
createFields(SchemaField field,
Object value,
float boost)
Given a SchemaField , create one or more IndexableField instances |
Query |
createSpatialQuery(QParser parser,

|
Query |
getFieldQuery(QParser parser,

String externalVal)
Throws UnsupportedOperationException() |
Query |
getRangeQuery(QParser parser,

String part1,
String part2,
boolean minInclusive,
boolean maxInclusive)
Returns a Query instance for doing range searches on this field type. |
SortField |
getSortField(SchemaField field,
boolean top)
Returns the SortField instance that should be used to sort fields of this type. |
ValueSource |
getValueSource(SchemaField field,
QParser parser)
called to get the default value source (normally, from the Lucene FieldCache.) |
protected void |
init(IndexSchema schema,
Map<String,String> args)
subclasses should initialize themselves with the args provided and remove valid arguments. |
boolean |
isPolyField()
A "polyField" is a FieldType that can produce more than one IndexableField instance for a single value, via the FieldType.createFields(org.apache.solr.schema.SchemaField, Object, float) method. |
void |
write(TextResponseWriter writer,
String name,
IndexableField f)
calls back to TextResponseWriter to write the field value |

currently passes part1 and part2 as null if they are '*' respectively. minInclusive and maxInclusive are both true
currently by SolrQueryParser but that may change in the future. Also, other QueryParser implementations may have
different semantics.
Sub-classes should override this method to provide their own range query implementation. They should strive to
handle nulls in part1 and/or part2 as well as unequal minInclusive and maxInclusive parameters gracefully.

public IndexableField createField(SchemaField field, Object value, float boost)
FieldType
By default, the indexed value is the same as the stored value (taken from toInternal()). Having a different representation for external, internal, and indexed would present quite a few problems given the current Lucene architecture. An analyzer for adding docs would need to translate internal->indexed while an analyzer for querying would need to translate external->indexed.
The only other alternative to having internal==indexed would be to have internal==external. In this case, toInternal should convert to the indexed representation, toExternal() should do nothing, and createField() should *not* call toInternal, but use the external value and set tokenized=true to get Lucene to convert to the internal(indexed) form.
:TODO: clean up and clarify this explanation.
