Constructor TermRangeQuery

TermRangeQuery(String, String, String, Boolean, Boolean)

Constructs a query selecting all terms greater/equal than lowerTerm but less/equal than upperTerm.

If an endpoint is null, it is said to be "open". Either or both endpoints may be open. Open endpoints may not be exclusive (you can't select all but the first or last term without explicitly specifying the term to exclude.)

Declaration
public TermRangeQuery(String field, String lowerTerm, String upperTerm, bool includeLower, bool includeUpper)
Parameters
Type Name Description
System.String field

The field that holds both lower and upper terms.
System.String lowerTerm

The term text at the lower end of the range
System.String upperTerm

The term text at the upper end of the range
System.Boolean includeLower

If true, the lowerTerm is included in the range.
System.Boolean includeUpper

If true, the upperTerm is included in the range.

TermRangeQuery(String, String, String, Boolean, Boolean, Globalization.CompareInfo)

Constructs a query selecting all terms greater/equal than lowerTerm but less/equal than upperTerm.

If an endpoint is null, it is said to be "open". Either or both endpoints may be open. Open endpoints may not be exclusive (you can't select all but the first or last term without explicitly specifying the term to exclude.)

If collator is not null, it will be used to decide whether index terms are within the given range, rather than using the Unicode code point order in which index terms are stored.

WARNING: Using this constructor and supplying a non-null value in the collator parameter will cause every single index Term in the Field referenced by lowerTerm and/or upperTerm to be examined. Depending on the number of index Terms in this Field, the operation could be very slow.

Declaration
public TermRangeQuery(String field, String lowerTerm, String upperTerm, bool includeLower, bool includeUpper, Globalization.CompareInfo collator)
Parameters
Type Name Description
System.String field
System.String lowerTerm

The Term text at the lower end of the range
System.String upperTerm

The Term text at the upper end of the range
System.Boolean includeLower

If true, the lowerTerm is included in the range.
System.Boolean includeUpper

If true, the upperTerm is included in the range.
System.Globalization.CompareInfo collator

The collator to use to collate index Terms, to determine their membership in the range bounded by lowerTerm and upperTerm.
