treatUnboundedRangeAsExistence

protected boolean treatUnboundedRangeAsExistence(SchemaField field)

For doubles and floats, unbounded range queries (which do not match NaN values) are not equivalent to existence queries (which do match NaN values).

The two types of queries are equivalent for all other numeric types.

Overrides:

treatUnboundedRangeAsExistence in class FieldType

Parameters:

field - the schema field

Returns:

false for double and float fields, true for all others

getSpecializedExistenceQuery

public org.apache.lucene.search.Query getSpecializedExistenceQuery(QParser parser,
                                                                   SchemaField field)

Override the default existence behavior, so that the non-docValued/norms implementation matches NaN values for double and float fields. The [* TO *] query for those fields does not match 'NaN' values, so they must be matched separately.

For doubles and floats the query behavior is equivalent to (field:[* TO *] OR field:NaN). For all other numeric types, the default existence query behavior is used.

Overrides:

getSpecializedExistenceQuery in class FieldType

Parameters:

parser - The QParser calling the method

field - The SchemaField of the field to search

Returns:

The Query instance.
