🔍 Semantic Search

Semantic searching, which involves understanding the intent and contextual meaning behind search queries, is yet another popular use-case of RAG. It has several popular use cases across various domains:

• Information Retrieval: Enhances search accuracy in databases and websites
• E-commerce: Improves product discovery in online shopping
• Customer Support: Powers smarter chatbots for effective responses
• Content Discovery: Aids in finding relevant media content
• Knowledge Management: Streamlines document and data retrieval in enterprises
• Healthcare: Facilitates medical research and literature search
• Legal Research: Assists in legal document and case law search
• Academic Research: Aids in academic paper discovery
• Language Processing: Enables multilingual search capabilities

Embedchain offers a simple yet customizable search() API that you can use for semantic search. See the example in the next section to know more.

Example: Semantic Search over Next.JS Website + Forum

Step 1: Set Up Your RAG Pipeline

First, let’s create your RAG pipeline. Open your Python environment and enter:

Create pipeline

from embedchain import App
app = App()

This initializes your application.

Step 2: Populate Your Pipeline with Data

Now, let’s add data to your pipeline. We’ll include the Next.JS website and its documentation:

Ingest data sources

# Add Next.JS Website and docs
app.add("https://nextjs.org/sitemap.xml", data_type="sitemap")

# Add Next.JS Forum data
app.add("https://nextjs-forum.com/sitemap.xml", data_type="sitemap")

This step incorporates over 15K pages from the Next.JS website and forum into your pipeline. For more data source options, check the Embedchain data sources overview.

Step 3: Local Testing of Your Pipeline

Test the pipeline on your local machine:

Search App

app.search("Summarize the features of Next.js 14?")
