KB search does not understand structured product data | Add system instruction to KB search

❓API❓KB❓Webchat
Hello dear community,

I am currently trying to build a product advisor as part of a shopping assistant in Voiceflow, the product data for this runs directly into the knowledge base. The relevant content is structured in both - the metadata and the chunks.

Unfortunately, when performing a search, the available information is sometimes not interpreted or searched correctly. To give a few examples:
Example 1: A user enters the following question in the search field: “I am looking for pants in size 26U.” Result: Pants are found, when I try this search in English, but when I try the same question in German "Ich suche eine Hose in Größe 26U", there is no result.
Example 2: A user enters the following question in the search field: “I am looking for an item with 46.00% Lyocell.” Result: No items are found, even though there are relevant articles in the KB (see screenshots attached).

Simple search queries such as “I am looking for a blue polo shirt for women” work fine.

I now have two questions in this context:
1. Why is the data stored in the knowledge base not being recognized and read correctly? Especially they are definitely available in the chunks and metadata.
2. Is there a way to provide the system with additional explanatory instructions for searching the knowledge base? I tried to include these instructions in a variable in the API block via “system” (see screenshot), but this does not seem to have any effect.
Example: “If the user asks for an item in a specific size, only items that are available in the requested size should be returned. The sizes in which an item is available can be found in the metadata under chunks.metadata._cf_alle_groessen.”

I am grateful for any help!

# Let your agents search the web 🔎 Hey everyone! We just released the web search tool for the agent step! Your agents can now automatically search the web for information, letting your agent supplement the LLM's knowledge and the data in its knowledge base with live, up-to-date information. Plus.... * You can restrict searches to specific domains, so your agent only searches sites that you own * This is a tool, so you remain in control of when the agent searches the web * Results are automatically summarized in a way that your agent can automatically understand Under the hood, we're using OpenAI's web search API. Give it a try, and let us know what you think! https://docs.voiceflow.com/changelog/native-web-search-tool
