Constructs a query selecting all terms greater/equal than
CopyC#
lowerTerm
 but less/equal than
CopyC#
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

CopyC#
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

CopyC#
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.

Type: System..::..String

[Missing <param name="field"/> documentation for "M:Lucene.Net.Search.TermRangeQuery.#ctor(System.String,System.String,System.String,System.Boolean,System.Boolean,System.Globalization.CompareInfo)"]

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

includeLower
Type: System..::..Boolean
If true, the
CopyC#

 is included in the range.
includeUpper
