Is the summary used in embeddings retrieval?

[Radu1999]

Is the summary of a document that is stored in meta used when embeddings are generated?

@Radu1999 Summaries stored in meta data are not used for the embeddings by default but you can activate that.
The parameter is called embed_meta_fields and expects a list of the names of the meta data fields that you would like to embed in addition to the document text:

haystack/haystack/nodes/retriever/dense.py

Line 1462 in 1144039

embed_meta_fields: Optional[List[str]] = None,

By the way, I would expect that using the summary in addition to the long text doesn't doesn't change much but it's worth a try.
