Technical Breakdown of Snowflake Universal Search—Features and Integration
Now, in this section, we will explain the technical integration, functionalities, and user interface features that make Snowflake Universal Search an effective tool for data discovery.
Integration with Snowflake Cortex
Snowflake Universal Search is integrated with Snowflake Cortex, leveraging its advanced machine learning (ML) and natural language processing (NLP) capabilities. This integration enhances the accuracy and relevance of search results by utilizing vector search functionality and large language models (LLMs). Snowflake Cortex provides the necessary infrastructure for running these ML models, allowing Snowflake Universal Search to handle complex queries efficiently.
Search Capabilities
Snowflake Universal Search can search a wide range of items, including database objects, data products, documentation, UDFs, and stored procedures. This broad search capability gurantees users can find various types of information within a single query.
Natural Language Processing
Snowflake Universal Search uses NLP capabilities to understand and process natural language queries. Users can input search terms as they would in a conversation, making the search process more intuitive and user-friendly. This capability is powered by LLMs that parse and interpret the intent behind user queries, providing highly relevant results.
Intelligent Query Understanding
Snowflake Universal Search handles misspellings and partial terms intelligently. This means that even if a user inputs an incomplete or incorrectly spelled term, the search engine can still provide relevant results.
Organized Search Results
Search results are categorized by type, helping users quickly find the specific information they need. Categories include:
- Tables & Views: Results related to tables and views.
- Databases & Schemas: Results related to databases and schemas.
- Functions & Procedures: Results related to user-defined functions and stored procedures.
- Marketplace: Results related to data products and other marketplace items.
- Documentation: Results related to documentation and help resources.
Metadata Search
Snowflake Universal Search indexes metadata such as:
- Names: Object names and column names.
- Comments: Comments associated with objects and columns.
- Tags: Tags associated with objects and columns.
However, it does not search within the contents of the database objects themselves, focusing instead on the metadata.
Embedding-Based Ranking
The search algorithm of Snowflake Universal Search uses embeddings—generated by a bi-encoder model to convert table names and other database objects into numerical representations. These embeddings are used to semantically rank results relative to a text query, making sure that the most relevant results are displayed at the top. The system is trained on a diverse dataset to handle various query types, including head queries (simple, one-word) and tail queries (complex, natural language).
Step-by-Step Guide to Navigate and Utilize Snowflake Universal Search
Let's dive into a detailed walkthrough on how to effectively use Snowflake Universal Search, from signing in to Snowsight to accessing and interpreting search results.
Step 1—Sign In to Snowsight
To access Snowflake Universal Search, users must first sign in to Snowflake. Once signed in, you will be able to access Snowsight, the web UI of Snowflake. It provides a centralized platform for data exploration, analysis, and collaboration within the Snowflake ecosystem.
Step 2—Accessing the Search Feature
Once logged in to Snowsight, you can access the Snowflake Universal Search feature by clicking on the "Search" option in the navigation menu.
This will open the Snowflake Universal Search interface, where you can enter your own search queries.
Step 3—Enter Search Terms
Now, in the Snowflake Universal Search input field, you can enter your own search terms. As mentioned earlier, one of the key strengths of Snowflake Universal Search is its ability to understand natural language queries. You can input the search terms using conversational language.
Tips and Best Practices for Entering Search Terms
1) Use natural language to describe your search intent
2) Experiment with different variations of search terms
3) Include relevant keywords or phrases related to your search topic
4) Leverage metadata information, such as object descriptions or tags, in your search queries
5) Don't worry about exact spellings; Snowflake Universal Search can handle variations and partial terms
Step 4—Review Search Results
After entering your search terms, Snowflake Universal Search will process the query and present the results in a categorized format. The search results will be organized into different categories, such as database objects, data products, documentation topics, and community knowledge base articles.
Each category will display a list of relevant results, providing you with a quick overview of the available data assets and resources related to your search query. You can easily navigate between categories and explore the various types of results.
Step 5—View Details of a Search Result
To gain more insights into a specific search result, click on each individual category to view additional details. Snowflake Universal Search displays all the necessary metadata information to navigate through the details of the search results.
For example:
1) To view only tables or views, select the "Tables & Views" category.
2) To view or open a worksheet or dashboard, select the "Worksheets & Dashboards" category.
3) To view a database or schema, select the "Databases & Schemas" category.
4) For user-defined functions or procedures, select the "Functions & Procedures" category.
As you can see, there are no results in the “Functions & Procedures” category, which means the search input you provided didn't match any entries. To resolve this, you can reset the search and try again.
5) To view all the data products available in Snowflake Marketplace, select the "Marketplace" category.
We will dive into more depth in Step 6.
6) For all documentation, select the "Documentation" category.
7) Also, there is an "All" category if you want to view all the Snowflake artifacts at once.
Note: If a category isn’t displayed, it means there are no results for that category or your active role does not have access to those results
Step 6—Access Marketplace Listings
If the search results include data products available on the Snowflake Marketplace, you can easily access and explore these listings directly from the Snowflake Universal Search interface. By clicking on a Marketplace listing, you can review detailed information about the data product, including its description, pricing, and terms of use.
Note: To access or purchase data products from the Snowflake Marketplace, you must have agreed to the Snowflake Provider and Consumer Terms and meet any additional legal requirements specified for the specific listing.

Limitations of Snowflake Universal Search
Snowflake Universal Search is a powerful and capable feature, but before you use it, you should understand its limitations.
1) Results based on active role privileges
Whenever you are searching for database objects within Snowsight, Snowflake Universal Search will only display results that the user's currently active role has privileges to view. So that users can only discover and access data assets they are authorized to work with.
2) Delays for New or Recreated Objects
Newly created database objects or objects that have been dropped and recreated (e.g., by scheduled tasks or automated pipelines) may take up to a few hours to appear in the search results. This delay is due to the indexing process that occurs in the background to ensure the search index remains up-to-date.
3) Supports only English
Currently, Snowflake Universal Search is optimized for search terms and queries in the English language. This limitation may challenge users operating in non-English languages.
4) Limited Regional availability
Snowflake Universal Search is available to accounts in a limited set of Snowflake regions:
- AWS EU (Zurich)
- GCP Europe West2 (London)
- GCP Europe West4 (Netherlands)
- GCP US Central1 (Iowa)
- GCP US East4 (N. Virginia)
Accounts in other regions may not have access to this feature until it is more widely rolled out.
5) Not available in VPS and government cloud regions
Snowflake Universal Search is not available for accounts hosted in Virtual Private Snowflake (VPS) or government cloud regions. These environments have specific security and compliance requirements that may necessitate additional considerations before Universal Search can be made available.
