query single or multiple indexes base on user question

Hi @WhiteFang_Jr @Logan M any recommendation for this? Thanks

Yea having an index per category and having good descriptions for each index, an agent or router would work fine

If I understand correclty, I need to classify books into categories, where each category will have its own index. For example, categories like "Fiction", "Non-Fiction", "Science", "History", etc.

For each category, you'll create a separate index and populate them with each books' description

Example Index Structure:

Index Name: Fiction
Description: Title 1, Author, Summary, Genre, Year, etc.
Description: Title 2, Author, Summary, Genre, Year, etc.
Description: Title 3, Author, Summary, Genre, Year, etc.
...

Index Name: Science
Description: Title 1, Author, Summary, Genre, Year, etc.
Description: Title 2, Author, Summary, Genre, Year, etc.
Description: Title 3, Author, Summary, Genre, Year, etc.
...


When performing a search query, route to category (index) to query against based on the user's input.

If a user is interested in "Science" books about "Quantum Mechanics", would direct the query specifically to the "Science" index.

Query Example:
User Query: "Quantum Mechanics"
Targeted Index(es): Science
Result: Books related to Quantum Mechanics from the Science category.

What is not clear for me how to create this category index, can you give me some example ? Then how to map to this category index what indexes to query for each book ?
Thanks

Once you have a category for a document, you can add it to the index for that category

Then you can use something like an agent or router to help use the correct index for the user query. Here's an example with an agent

I'm not using OpenAI, will this agent work with Claude or other LLM ?

yea, you can do the same with a react agent (this works with any LLM)

And actually, if you are using claude, you can use their function calling

Many thanks, I will try
