One of our biggest fears for Vectorize is that all metadata filters have to be created at index creation.

Wondering if there are plans to allow additional metadata filters to be created after index creation.

Thanks

Hi all, I'm new to Vectorize and have been working through this tutorial (request to documentation author: we could really do with a summary of what the code in step 6 does, after the code.)

We previously vectorised a note ("pepparoni is the best pizza topping"), and saved it to the Vectorize DB. I get all that. What I'm less clear on is step 6. I send in a question, presumably something like "what's the best pizza topping?", and then we retrieve the vectors relating to the note closest to that question.

So my question here is: what powers CF's ability to associate that question with that note? Is it because both contain the word pizza? If instead I'd asked "what is the best topping for a common Italian dish?", would it have still returned the vector (my note)?

Mitya•10/13/24, 6:42 PM

Right, so it would make that link even though I myself have only given it one note and one question? (i.e. this suggests preexisting knowledge)

Isaac McFadyen•10/13/24, 6:43 PM

As for if you have more than 1 vector though, yes, the model that generates the vectors understands association between topics.

Isaac McFadyen•10/13/24, 6:43 PM

If you use a proper embedding model it also understands actual text, not just words - i.e. it would understand your second case there.

a proper embedding model?

Isaac McFadyen•10/13/24, 6:44 PM

Vectorize itself is just a DB that stores the vectors. You could throw any vector in there, not just word embeddings - I've used it for facial recognition embeddings, for example.

Isaac McFadyen•10/13/24, 6:44 PM

Yes.

Mitya•10/13/24, 6:45 PM

OK great. So it's not like, with just one vector in the DB, it would return that vector whatever my question was?

Isaac McFadyen•10/13/24, 6:45 PM

With one vector it would, yeah - that's what Leo was saying. You request the "top <n>" vectors, so it'll always return that 1 vector since you can't request "top 0"

Mitya•10/13/24, 6:45 PM

Ah, gotcha. So this becomes useful only once you've pumped it full of a lot of stuff?

Isaac McFadyen•10/13/24, 6:46 PM

Depends on your use-case, but it will also return a distance.

Mitya•10/13/24, 6:46 PM

Otherwise my users asking "what's the capital of Mongolia" are going to be told about pizza

Isaac McFadyen•10/13/24, 6:46 PM

So if you have 1 vector about pizza, and the user asks about Mongolia, and the distance is huge you can return a preset "sorry, I don't know" response.

Isaac McFadyen•10/13/24, 6:46 PM

Whereas if the distance is small, the question is likely about pizza.

Mitya•10/13/24, 6:46 PM

OK! That makes sense. I don't think the tut discusses distance

Isaac McFadyen•10/13/24, 6:47 PM

Ah OK, yeah - I'm pretty sure it returns distances (or it did last I used it)

Mitya•10/13/24, 6:49 PM

Similarity = distance? The tut (step 6) seems to assume that if it retrieved a vector that it's fine to use with the LLM. No checks on distance/similarity, hence my question.

Mitya•10/13/24, 6:50 PM

Ah that's true. So distance is more important if there's no LLM in play i.e. you just want to return the note, I guess?

Mitya•10/13/24, 6:51 PM

Great, thanks everyone.

Isaac McFadyen•10/14/24, 4:05 AM

Also

distance = 1 - similarity

distance = 1 - similarity

similarity of 1 = perfect match
similarity of 0 = absolutely no match
distance of 0 = perfect match
distance of 1 = absolutely no match

yevgen•10/14/24, 10:31 AM

You could use https://developers.cloudflare.com/vectorize/best-practices/insert-vectors/#metadata to add multiple fields describing vectors and index each of the metadata fields separately to support filtering.

Cloudflare Docs

Insert vectors | Vectorize

Vectorize indexes allow you to insert vectors at any point: Vectorize will optimize the index behind the scenes to ensure that vector search remains efficient, even as new vectors are added or existing vectors updated.

kingmesal•10/14/24, 1:38 PM

Fair point. Those have been there. I meant a way to view / query something from the dashboard, similar to KV, or D1. An abiltity to perform a sanity check. e.g. In pinecone I had a bug once where I was removing a bunch of vectors before inserting a batch up new records and I had a bug, it died before inserting the new records. In their dashboard I had the ability to see some basic in formation to know that the data was gone.

kingmesal•10/14/24, 1:46 PM

Sure, here are a couple of the examples, in priority order.

I have a few different use cases for putting dates (number format, seconds of ms is normal) on the vectors as a way to only bring back candidates after (>=) X and before (<) Y. Basically, Temporal limitations.
I have a list of arbitrary attributes, call it categorical information. Filter vectors where X is in that list. Or filter vectors where X is not in that list.

EndiM•10/19/24, 6:26 AM

Hi. Would it apply if i were to upsert on that existing data? So if i create a new metadata index, and upsert the data, can that metadata be used as a filter? Since it overrides, im guessing yes, but i need to make sure!

EndiM•10/19/24, 6:30 AM

Also, one other question. On the filter operation there is only eq and ne. Is there a way to use contains logic? Ex: you search for an address, but on the results its not in the 20 topk. If i were to have a containy on the adress metadata tho, i would force my vector search to isolate my responses on this search option.

Daniel•10/19/24, 5:38 PM

Hi all! I have a beginner question. I am trying to use Vectorize with my NextJS Cloudflare Pages website. In this tutorial https://developers.cloudflare.com/workers-ai/tutorials/build-a-retrieval-augmented-generation-ai/ they say to use

npx wrangler dev --remote

npx wrangler dev --remote

to run locally and iterate.

When I run that, I see:

✘ [ERROR] It looks like you've run a Workers-specific command in a Pages project.

  For Pages, please run `wrangler pages dev` instead.

✘ [ERROR] It looks like you've run a Workers-specific command in a Pages project.

I need to use

because of:

▲ [WARNING] Vectorize bindings are not currently supported in local mode. Please use --remote if you are working with them.

And without that, I see:

The AI binding and KV binding are working fine, no issues there, but I can't seem to get the Vectorize binding to show up at all. Maybe I'm making an obvious mistake -- I'm somewhat new to Cloudflare. Any help appreciated, thank you!

Metadata filtering | Vectorize

In addition to providing an input vector to your query, you can also filter by vector metadata associated with every vector. Query results will only include vectors that match the filter criteria, meaning that filter is applied first, and the topK results are taken from the filtered set.

why is it onnly limited to 100 indexes per account, can we request to increase this?

If users don't need to access each other's vectors (if they should be silo'ed), then yes, creating a namespace per user is OK, although right-now there's a 1k namespaces limit per index.
If they should be able to share them, then they should share a namespace and you use metadata filters instead for user segregation.

So at the end of the day, you'll have to think what suits your use-case the best.
