Class DocTermOrdsRangeFilter

A range filter built on top of a cached multi-valued term field (in IFieldCache).

Like FieldCacheRangeFilter, this is just a specialized range query versus using a TermRangeQuery with DocTermOrdsRewriteMethod: it will only do two ordinal to term lookups.

NewBytesRefRange(String, BytesRef, BytesRef, Boolean, Boolean)

Creates a BytesRef range filter using GetTermsIndex(AtomicReader, String, Single). This works with all fields containing zero or one term in the field. The range can be half-open by setting one of the values to null.

Declaration
public static DocTermOrdsRangeFilter NewBytesRefRange(string field, BytesRef lowerVal, BytesRef upperVal, bool includeLower, bool includeUpper)
Parameters
Type Name Description
System.String field
BytesRef lowerVal
BytesRef upperVal
System.Boolean includeLower
System.Boolean includeUpper
