Pinecone, a vector database designed for AI purposes, simplifies authorization via metadata filtering. This methodology permits vectors to be tagged with metadata (e.g., person roles or departments) and filtered throughout search operations. It’s notably efficient in AI chatbot eventualities, the place you wish to be sure that solely licensed customers can entry particular information primarily based on predefined metadata guidelines.
Understanding vector similarity search
In vector similarity search, we construct vector representations of knowledge (reminiscent of photos, textual content, or recipes), retailer them in an index (a specialised database for vectors), after which search that index with one other question vector.
This is identical precept that powers Google’s search engine, which identifies how your search question aligns with a web page’s vector illustration. Equally, platforms like Netflix, Amazon, and Spotify depend on vector similarity search to advocate reveals, merchandise, or music by evaluating customers’ preferences and figuring out comparable behaviors inside teams.
Nonetheless, with regards to securing this information, it’s important to implement authorization filters in order that search outcomes are restricted primarily based on the person’s roles, departments, or different context-specific metadata.
Introduction to metadata filtering
Metadata filtering provides a layer of authorization to the search course of by tagging every vector with further context, reminiscent of person roles, departments, or timestamps. For instance, vectors representing paperwork could embrace metadata like:
- Person roles (e.g., solely “managers” can entry sure paperwork)
- Departments (e.g., information accessible solely to the “engineering” division)
- Dates (e.g., proscribing information to paperwork from the final yr)
This filtering ensures that customers solely retrieve outcomes they’re licensed to view.
Challenges in metadata filtering: pre-filtering vs. post-filtering

When making use of metadata filtering, two conventional strategies are generally used: Pre-filtering and Publish-filtering.
- Pre-filtering applies the metadata filter earlier than the search, limiting the dataset to related vectors. Whereas this ensures that solely licensed vectors are thought of, it disrupts the effectivity of Approximate Nearest Neighbor (ANN) search algorithms, resulting in slower, brute-force searches.
- Publish-filtering, in distinction, performs the search first and applies the filter afterward. This avoids slowdowns from pre-filtering however dangers returning irrelevant outcomes if not one of the prime matches meet the filtering situations. For instance, you would possibly retrieve fewer or no outcomes if not one of the prime vectors go the metadata filter.
To resolve these points, Pinecone introduces Single-Stage Filtering. This methodology merges the vector and metadata indexes, permitting for each velocity and accuracy. By implementing entry controls inside a single-stage filtering course of, Pinecone optimizes each efficiency and safety in real-time searches.
Making use of metadata filtering for authorization: code instance
Now, let’s discover methods to implement metadata filtering in Pinecone for a real-world AI chatbot use case. This instance demonstrates methods to insert vectors with metadata after which question the index utilizing metadata filters to make sure licensed entry.
Open menu
import pinecone
# Initialize Pinecone
pinecone.init(api_key="your_api_key", atmosphere="us-west1-gcp")
# Create an index
index_name = "example-index"
if index_name not already created:
pinecone.create_index(index_name, dimension=128, metric="cosine")
# Hook up with the index
index = pinecone.Index(index_name)
# Insert a vector with metadata
vector = [0.1, 0.2, 0.3, ..., 0.128] # Instance vector
metadata = {
"user_id": "user123",
"position": "admin",
"division": "finance"
}
# Upsert the vector with metadata
index.upsert(vectors=[("vector_id_1", vector, metadata)])
On this instance, we’ve inserted a vector with related metadata, such because the user_id
, position
, and division
, which might later be used for implementing entry management. The following step entails querying the index whereas making use of a metadata filter to limit the outcomes primarily based on the person’s authorization profile.
Open menu
# Querying the index, proscribing outcomes primarily based on metadata
query_vector = [0.15, 0.25, 0.35, ..., 0.128]
filter = {
"user_id": "user123", # Solely retrieve vectors belonging to this person
"position": {"$eq": "admin"} # Non-obligatory: match position
}
# Carry out the question with metadata filter
outcomes = index.question(queries=[query_vector], filter=filter, top_k=5)
# Show outcomes
for end in outcomes["matches"]:
print(outcome)
By making use of the metadata filter throughout the question, we be sure that solely vectors that match the person’s metadata (e.g., person ID and position) are returned, successfully implementing authorization in real-time.
Implementing advanced filters for authorization
Metadata filtering can be prolonged to deal with extra advanced, multi-dimensional authorization eventualities. As an illustration, we are able to filter outcomes primarily based on a number of situations, reminiscent of limiting search outcomes to paperwork inside a particular division and date vary.
Open menu
# Question with a number of metadata situations
filter = {
"division": {"$eq": "finance"},
"date": {"$gte": "2023-01-01", "$lt": "2023-12-31"}
}
outcomes = index.question(queries=[query_vector], filter=filter, top_k=5)
# Show outcomes
for end in outcomes["matches"]:
print(outcome)
This mixture of vector similarity search and metadata filtering creates a strong framework for fine-grained authorization. It ensures that AI chatbots can ship each excessive efficiency and safe, context-driven responses by limiting search outcomes to licensed customers primarily based on a number of dimensions reminiscent of position, division, and timeframe.

Supabase: Row-level safety for vector information
Fig: RLS with Postgres and Supabase
Metadata filtering is good for broad entry management primarily based on classes or tags (e.g., limiting search outcomes by division or position). Nonetheless, it falls brief when strict management is required over who can view, modify, or retrieve particular data.
In enterprise programs that depend on relational databases, reminiscent of monetary platforms, entry usually must be enforced right down to particular person transaction data or buyer information rows. Supabase row-level safety (RLS) permits this by defining insurance policies that implement fine-grained permissions on the row degree, primarily based on person attributes or exterior permission programs utilizing International Knowledge Wrappers (FDWs).
Whereas metadata filtering excels at managing entry to non-relational, vector-based information—excellent for AI-powered searches or suggestion programs—Supabase RLS affords exact, record-level management, making it a greater match for environments that require strict permissions and compliance.

Implementing RLS for retrieval-augmented technology (RAG)
In retrieval-augmented technology (RAG) programs, like vector similarity searches in Pinecone, paperwork are damaged into smaller sections for extra exact search and retrieval.
Right here’s methods to implement RLS on this use case:
Open menu
-- Monitor paperwork/pages/information/and many others
create desk paperwork (
id bigint major key generated at all times as id,
title textual content not null,
owner_id uuid not null references auth.customers (id) default auth.uid(),
created_at timestamp with time zone not null default now()
);
-- Retailer content material and embedding vector for every part
create desk document_sections (
id bigint major key generated at all times as id,
document_id bigint not null references paperwork (id),
content material textual content not null,
embedding vector(384)
);
On this setup, every doc is linked to an owner_id that determines entry. By enabling RLS, we are able to prohibit entry to solely the proprietor of the doc:
Open menu
-- Allow row degree safety
alter desk document_sections allow row degree safety;
-- Setup RLS for choose operations
create coverage "Customers can question their very own doc sections"
on document_sections for choose to authenticated utilizing (
document_id in (
choose id from paperwork the place (owner_id = (choose auth.uid()))
)
);
As soon as RLS is enabled, each question on document_sections will solely return rows the place the at present authenticated person owns the related doc. This entry management is enforced even throughout vector similarity searches:
Open menu
-- Carry out inside product similarity primarily based on a match threshold
choose *
from document_sections
the place document_sections.embedding <#> embedding < -match_threshold
order by document_sections.embedding <#> embedding;
This ensures that semantic search respects the RLS insurance policies, so customers can solely retrieve the doc sections they’re licensed to entry.
Dealing with exterior person and doc information with overseas information wrappers
In case your person and doc information reside in an exterior database, Supabase’s help for International Knowledge Wrappers (FDW) lets you connect with an exterior Postgres database whereas nonetheless making use of RLS. That is particularly helpful in case your present system manages person permissions externally.
Right here’s methods to implement RLS when coping with exterior information sources:
Open menu
-- Create overseas tables for exterior customers and paperwork
create schema exterior;
create extension postgres_fdw with schema exterior;
create server foreign_server
overseas information wrapper postgres_fdw
choices (host '<db-host>', port '<db-port>', dbname '<db-name>');
create person mapping for authenticated
server foreign_server
choices (person 'postgres', password '<user-password>');
import overseas schema public restrict to (customers, paperwork)
from server foreign_server into exterior;
When you’ve linked the exterior information, you may apply RLS insurance policies to filter doc sections primarily based on exterior information:
Open menu
create desk document_sections (
id bigint major key generated at all times as id,
document_id bigint not null,
content material textual content not null,
embedding vector(384)
);
-- RLS for exterior information sources
create coverage "Customers can question their very own doc sections"
on document_sections for choose to authenticated utilizing (
document_id in (
choose id from exterior.paperwork the place owner_id = current_setting('app.current_user_id')::bigint
)
);
On this instance, the app.current_user_id session variable is ready initially of every request. This ensures that Postgres enforces fine-grained entry management primarily based on the exterior system’s permissions.
Whether or not you’re managing a easy user-document relationship or a extra advanced system with exterior information, the mixture of RLS and FDW from Supabase supplies a scalable, versatile resolution for implementing authorization in your vector similarity searches.
