lowerTermbut 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.)
field- An interned field that holds both lower and upper terms.
lowerTermText- The term text at the lower end of the range
upperTermText- The term text at the upper end of the range
includeLower- If true, the
lowerTermis included in the range.
includeUpper- If true, the
upperTermis included in the range.
collator- The collator to use to collate index Terms, to determine their membership in the range bounded by
