Ridgeline wants one retriever to answer questions against a single Data Library source that mixes exact lab-code references and loosely phrased explanatory text within the same guideline documents. Is an ensemble retriever required, or is there a simpler option?
Select an answer to reveal the explanation.
Short Explanation
You don’t need an ensemble just because your guideline mixes exact codes with explanatory text. A single retriever using hybrid search can handle both matching styles within that one source.
Full Explanation
A single individual retriever configured with hybrid search is sufficient for Ridgeline’s mixed guideline source: combining keyword and vector matching lets it address exact lab-code references as well as loosely phrased explanatory text, without requiring an ensemble. The claim that an ensemble is required because one retriever can use only one search method is incorrect; hybrid search combines matching methods within one retriever. The claim that no retriever configuration can handle mixed content in one source is also incorrect, since hybrid search can address both patterns there. Nor must the content be divided into separate Data Library sources before retrieval is possible. As an exam caveat, an ensemble may be useful when retrieval needs to span distinct sources, but mixed content in one source alone does not make it necessary. As a practical check, confirm that the individual retriever is configured for hybrid search, then test a query using an exact lab code and another phrased as a paraphrase of the guideline text.
