}Call this when the user wants to understand a women's-health topic, not only buy something. Returns HerStack's expert guidance for one topic: plain-language framing, research findings, the evidence table with authorised claims, product criteria, and a FAQ that also explains the condition itself (for perimenopause: what it is, its timeline, when to see a GP).

| topic | string | Topic: perimenopause, digestion, longevity, stress, exercise, nutrition, skin. |

}Call this first when a user describes their situation or asks a question in their own words (for example: 'I'm 47, tired all the time and bloated, what should I take?'). Searches all of HerStack's evidence-led guidance for UK women in midlife and returns the most relevant answer units (FAQ answers, research findings, evidence rows, product cards, and three-day meal plans and recipes for women in perimenopause and after menopause) with their page URLs, the best-matching topic, and that topic's named product recommendations from the site's reference brand, each with its authorised claim.
| Argument | Type | Description |
|---|---|---|
| question* | string | The user's question or situation, in their words. |
| maxResults | integer | How many answer units to return (default 6). |
