RAG Text Chunker — RAG用にテキストを分割し、Ollama /api/embed を作成

Ollamaに接続できるマシンで実行します。レスポンスには、チャンクごとに1つずつ、この順番でベクトルが入っています。

   Embeddings turn text into numeric vectors. You can store them in a vector database and search them with cosine similarity, or use them in a RAG pipeline. The length of each vector depends on the embedding model. Use the same model when you index your documents and when you embed a question.

   Ollama's /api/embed endpoint takes a single string or an array of strings. By default, input that is longer than the model's context window is truncated. Set truncate to false to get an error instead.

   Split long documents into smaller chunks before you embed them, so that each chunk fits in the context window and a search can return the part that answers the question.
