类名称:Relation
方法名:getSimilarityRangeQuery

Relation.getSimilarityRangeQuery介绍

[英]Get a range query object for the given similarity query. (Range queries in ELKI refers to radius-based ranges, not rectangular query windows.) When possible, this will use an index, but it may default to an expensive linear scan. Hints include:

  • Double: Maximum query range
  • DatabaseQuery#HINT_BULK bulk query needed
    [中]获取给定相似性查询的范围查询对象。(ELKI中的范围查询指的是基于半径的范围,而不是矩形查询窗口。)如果可能,这将使用索引,但它可能默认为昂贵的线性扫描。提示包括:
    *Double:最大查询范围
    *数据库查询#提示_需要批量查询
