     开发GIN索引的主要目的是为了让openGauss支持高度可伸缩的全文索引，并且常常会遇见全文索引返回海量结果的情形。而且，这经常发生在查询高频词的时候，因而这样的结果集没什么用处。因为从磁盘读取大量记录并对其进行排序会消耗大量资源，这在产品环境下是不能接受的。
 
-    为了控制这种情况，GIN索引有一个可配置的返回结果行数上限的配置参数gin\_fuzzy\_search\_limit。缺省值0表示没有限制。如果设置了非零值，那么返回结果就是从完整结果集中随机选择的一部分。
+    为了控制这种情况，GIN索引有一个可配置的返回结果行数的软上限的配置参数gin\_fuzzy\_search\_limit。缺省值0表示没有限制。如果设置了非零值，那么返回结果就是从完整结果集中随机选择的一部分。“软上限”的意思是返回结果的实际数量可能与指定的限制有偏差，这取决于查询和系统随机数生成器的质量。
