public class CollationField
extends FieldType

Field for collated sort keys. These can be used for locale-sensitive sort and range queries.

This field can be created in two ways:

• Based upon a system collator associated with a Locale.
• Based upon a tailored ruleset.

Using a System collator:

• language: ISO-639 language code (mandatory)
• country: ISO-3166 country code (optional)
• variant: vendor or browser-specific code (optional)
• strength: 'primary','secondary','tertiary', or 'identical' (optional)
• decomposition: 'no','canonical', or 'full' (optional)

Using a Tailored ruleset:

• custom: UTF-8 text file containing rules supported by RuleBasedCollator (mandatory)
• strength: 'primary','secondary','tertiary', or 'identical' (optional)
• decomposition: 'no','canonical', or 'full' (optional)

Since:

solr 4.0

Method Detail

init

protected void init(IndexSchema schema,
                    Map<String,String> args)

Description copied from class: FieldType

subclasses should initialize themselves with the args provided and remove valid arguments. leftover arguments will cause an exception. Common boolean properties have already been handled.

Overrides:

init in class FieldType

write

public void write(TextResponseWriter writer,
                  String name,
                  IndexableField f)
           throws IOException

Description copied from class: FieldType

calls back to TextResponseWriter to write the field value

Specified by:

write in class FieldType

Throws:

IOException

getSortField

public SortField getSortField(SchemaField field,
                              boolean top)

Description copied from class: FieldType

Returns the SortField instance that should be used to sort fields of this type.

Specified by:

getSortField in class FieldType

See Also:

SchemaField.checkSortability()

getUninversionType

public UninvertingReader.Type getUninversionType(SchemaField sf)

Description copied from class: FieldType

DocValues is not enabled for a field, but it's indexed, docvalues can be constructed on the fly (uninverted, aka fieldcache) on the first request to sort, facet, etc. This specifies the structure to use.

Specified by:

getUninversionType in class FieldType

Parameters:

sf - field instance

Returns:

type to uninvert, or null (to disallow uninversion for the field)

getIndexAnalyzer

public Analyzer getIndexAnalyzer()

Description copied from class: FieldType

Returns the Analyzer to be used when indexing fields of this type.

This method may be called many times, at any time.

Overrides:

getIndexAnalyzer in class FieldType

See Also:

FieldType.getQueryAnalyzer()

getQueryAnalyzer

public Analyzer getQueryAnalyzer()

Description copied from class: FieldType

Returns the Analyzer to be used when searching fields of this type.

This method may be called many times, at any time.

Overrides:

getQueryAnalyzer in class FieldType

See Also:

FieldType.getIndexAnalyzer()

getRangeQuery

public Query getRangeQuery(QParser parser,
                           SchemaField field,
                           String part1,
                           String part2,
                           boolean minInclusive,
                           boolean maxInclusive)

Description copied from class: FieldType

Returns a Query instance for doing range searches on this field type. SolrQueryParser 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.

Overrides:

getRangeQuery in class FieldType

Parameters:

parser - the QParser calling the method

field - the schema field

part1 - the lower boundary of the range, nulls are allowed.

part2 - the upper boundary of the range, nulls are allowed

minInclusive - whether the minimum of the range is inclusive or not

maxInclusive - whether the maximum of the range is inclusive or not

Returns:

a Query instance to perform range search according to given parameters

checkSchemaField

public void checkSchemaField(SchemaField field)

Description copied from class: FieldType

Check's SchemaField instances constructed using this field type to ensure that they are valid.

This method is called by the SchemaField constructor to check that its initialization does not violate any fundemental requirements of the FieldType. The default implementation does nothing, but subclasses may chose to throw a SolrException if invariants are violated by the SchemaField.

Overrides:

checkSchemaField in class FieldType

createFields

public List<IndexableField> createFields(SchemaField field,
                                         Object value,
                                         float boost)

Description copied from class: FieldType

Given a SchemaField, create one or more IndexableField instances

Overrides:

createFields in class FieldType

Parameters:

field - the SchemaField

value - The value to add to the field

boost - The boost to apply

Returns:

An array of IndexableField

See Also:

FieldType.createField(SchemaField, Object, float), FieldType.isPolyField()

marshalSortValue

public Object marshalSortValue(Object value)

Description copied from class: FieldType

Convert a value used by the FieldComparator for this FieldType's SortField into a marshalable value for distributed sorting.

Overrides:

marshalSortValue in class FieldType

unmarshalSortValue

public Object unmarshalSortValue(Object value)

Description copied from class: FieldType

Convert a value marshaled via FieldType.marshalSortValue(java.lang.Object) back into a value usable by the FieldComparator for this FieldType's SortField

Overrides:

unmarshalSortValue in class FieldType
