-An [AI enrichment pipeline](cognitive-search-concept-intro.md) that makes calls to a Text Analytics resource for [entity recognition](cognitive-search-skill-entity-recognition.md), [key phrase extraction](cognitive-search-skill-keyphrases.md), [sentiment analysis](cognitive-search-skill-sentiment.md), [language detection](cognitive-search-skill-language-detection.md), and [PII detection](cognitive-search-skill-pii-detection.md) is subject to data limits. The maximum size of a record should be 50,000 characters as measured by [`String.Length`](https://docs.microsoft.com/dotnet/api/system.string.length). If you need to break up your data before sending it to the sentiment analyzer, use the [Text Split skill](cognitive-search-skill-textsplit.md).
