        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.

      • getUninversionType

        public UninvertingReader.Type getUninversionType​(SchemaField sf)
        Description copied from class: FieldType

        If 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.

        This method will not be used if the field is (effectively) uninvertible="false"

        Specified by:
        getUninversionType in class FieldType
        sf - field instance
        type to uninvert, or null (to disallow uninversion for the field)

                                                            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.
