Text Embedding (v1) 🔍

This example embeds local markdown files, stores the chunks + embeddings in Postgres (pgvector), and provides a simple semantic-search query demo.

Prerequisites

• A running Postgres with the pgvector extension available
• POSTGRES_URL set, e.g.

export POSTGRES_URL="postgres://cocoindex:cocoindex@localhost/cocoindex"

Run

Install deps:

pip install -e .

Build/update the index (writes rows into Postgres):

cocoindex update main.py

Query:

python main.py query "what is self-attention?"

Note: this example does not create a vector index; queries will do a sequential scan.
