Similarity = distance? The [tut (step 6)](https://developers.cloudflare.com/workers-ai/tutorials/bui

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.

MityaOP•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?

MityaOP•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.

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.

But when I do that, I see:

❯ npx wrangler pages dev --remote

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.

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.

For the metadata filtering, is it ok to do {"attribute":{"$ne", null} } ?

another question is that any upsert support that only updates the metadata based on id ? Whats the recommended way to update metadata?

freddw•10/26/24, 7:27 PM

Is best practice for supporting more complicated query semantics than just filtering to upsert vectors with a metadata field containing foreign keys to D1 records? Then implement your own pre/post filtering between the two?

freddw•10/26/24, 7:32 PM

as an aside it seems like if the reasoning behind launching vectorize as a separate product from D1 is that either sqlite did not support vector search at the time of launch, or that it was not considered an ideal substrate for vector search, it could be nice to integrate vectorize within D1 under the hood (with restrictions to what is possible within vectorize databases) so that users could write simpler queries/have easier setup/less to manage. Because at the end of the day a lot of people (like me) will want to combine topK with joins and it'd be nice to not have to implement some of that myself, assuming I'm not missing something re: the current impl

yanlin•10/28/24, 12:22 AM

Given the limitations of the meta-filtering operation, I have to leverage a nested key structure as documented:
{ "pandas.nice": 42 }
// looks for { "pandas": { "nice": 42 } }

However, when I attempt to upsert metadata where the key contains a JSON object, as specified in the documentation, I encounter the following error:

VECTOR_UPSERT_ERROR (code = 40019): invalid metadata for vector id=“jhbqpwft0qogbr1fs6re-0”; the metadata JSON object cannot contain JSON objects.

I’m not sure what to do next. Does anyone have any suggestions? Thanks!

Rahul gangotri•10/29/24, 7:13 AM

Quick question

Why do we need to create metadata index and even if we have to create, why only 1 key at a time and upto 10 index is the limit? While upstash allows to filter on metadata normally on all metadata
Can we also expect glob and more type of searches operators along with eq and neq

Like : contains , IN, not in, glob, pattern match, and , or etc

can we also have hybrid search like a cosine similarity search with Full text search as well for better search in future?
