# マッチ式ツールの正規表現
match expression ツールは、製品SKU、カテゴリ、またはプロモコードに含まれる文字の組み合わせの一部が分かっており、これらの文字の組み合わせをコンバージョンに付随して渡されるSKU、カテゴリ、またはプロモコードに照合したい場合に使用します。このツールを使用する必要があるのは、一覧にある項目の完全なリストがない場合のみです。 [例外リスト](/brand/ja/what-would-you-like-to-learn-about/account-administration/program-settings/exception-lists/create-category-and-sku-exception-lists.md).
1. 上部ナビゲーションバーで、  **\[ユーザープロフィール] → 設定**.
2. 右側の列の下に *例外リスト*で、 *例外リスト* セクションで、 **SKU**.
3. 選択 **新しいSKUリストを追加**.
4. 選択 **詳細設定を表示** .
5. Match Expressions フィールドには、match expression ツールの重要な要素が2つあります。

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation by asking a question.
Perform an HTTP GET request on the following URL with the `ask` and `goal` query parameters:
```
GET https://help.impact.com/brand/ja/what-would-you-like-to-learn-about/platform-features/promo-codes/regular-expression/match-expression-tool-regex.md?ask=&goal=
```
`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is what the user is ultimately trying to achieve, the reason they need the answer. Sharing it helps GitBook give you a better, more relevant answer. A goal is most helpful when it describes the outcome the user wants rather than restating the question. For example, with `ask=how do I create an API token`, a goal like `automate deployments from our CI pipeline` lets GitBook tailor the answer to that use case.
The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.
Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
