求翻译：如果搜索到的记录期望值 相差不大，可以视为这几个记录属于同一类别，如果期望值 相差很大我们可以认为这个记录属于不同类别。是什么意思？

If the search of records or less expected, these records can be regarded as belonging to the same category, if very different expectations that we can think that this record belongs to a different category.

If you search the records of expectations, there is not much difference between the several records can be regarded as belonging to the same category, if you expect significant variations in the value we can think that this record fall into different categories.

If searches the record expected value difference is not big, may regard as these records to belong to the identical category, if expected value difference we may think very greatly this record belongs to the different category.

If you search for records to expect comparable, can be seen as the few records that belong to the same category, if expectations vary greatly, we can think that the record belongs to a different category.
