如何在多个表和“求和值列”中查找值（如果存在）？

Question

当查询表中存在包含该品牌的词组时，我要在第一个表上对儿童品牌进行汇总，以在各行中汇总这些品牌的搜索量。

+--------------------+-------------------+
|    Kids Brands     | Search Volume Sum |
+--------------------+-------------------+
| adidas             |                   |
| Ben Sherman        |                   |
| Calvin Klein       |                   |
| Calvin Klein Jeans |                   |
| Diesel             |                   |
+--------------------+-------------------+

我有具有以下值的第二个查找表

+-----------------------+-----------------------+
|        Keyword        | Avg. monthly searches |
+-----------------------+-----------------------+
| adidas boys           |                  1000 |
| adidas for girls      |                  2900 |
| adidas kids           |                  5400 |
| alpha industries boys |                    20 |
| alpha industries kids |                    90 |
| ben sherman boys      |                    50 |
| ben sherman kids      |                   170 |
| boss boy              |                   390 |
+-----------------------+-----------------------+

最终输出应为

+--------------------+-------------------+
|    Kids Brands     | Search Volume Sum |
+--------------------+-------------------+
| adidas             |              9300 |
| Ben Sherman        |               220 |
| Calvin Klein       |                 0 |
| Calvin Klein Jeans |                 0 |
| Diesel             |                 0 |
+--------------------+-------------------+
