+## Evaluate Pure Text Retrieval Models on Refined Vidore Tasks 
+
+The original Vidore dataset contain multiple text chunks per image to evaluate text retrieval models on them.
+Those text chunks are  extracted from the document pages using different tools like [Unstructured](https://github.com/Unstructured-IO/unstructured), OCR models, and LLMs.
+For evaluating text retrieval models on our filtered versions of the Vidore datasets, you can use the datasets in the collection `https://huggingface.co/collections/jinaai/jina-vdr-vidoreocr-tasks-6852cfc55ccf837e7fecfa1b`.
+
+It is also possible to evaluate jina-embeddings-v4 and other vision retrieval models on them. This however takes more time and should lead to the same evaluation results as running the vesions of the datasets in the Jina VDR collection.
