establish a scan according to the relation given and startPos : the start-scan object , null means scan all values. The relation is from com.j_spaces.client.TemplateMatchCodes: LT, LE, GT, GE (other codes are not relevant) endPos- key up to (or null if no limit in index) endPosInclusive : is the endPos up to (or down to) and including ? returns an ExtendedIndexIterator object which enables scanning the ordered index, Null if no relevant elements to scan
