-If you have large documents, insert a chunking step into indexing and query workflows that breaks up large text. When using [integrated vectorization](vector-search-integrated-vectorization.md), a default chunking strategy using the [Text Split skill](./cognitive-search-skill-textsplit.md) is common. You can also apply a custom chunking strategy using a [custom skill](cognitive-search-custom-skill-web-api.md).
