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()

getAnalyzer

public Analyzer getAnalyzer()

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:

getAnalyzer 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.getAnalyzer()

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

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
