How to Discover Assets of Interest
Search is at the front and center of OpenMetadata and is available in the top Menu bar across all the different pages. OpenMetadata simplifies data discovery with the following strategies.
Keyword Search
A simple yet powerful way to find assets by typing the name or description from the search interface. The search suggest will display matching data assets in several categories. Your query will retrieve all matching tables, topics, dashboards, pipelines, ML models, containers, glossaries, and tags. Your queries will match names for data assets and their components, such as column names for tables and chart names for dashboards. The queries will also match the descriptions used.

Multiple filter options further help to narrow down the search by Owner, Tag, Tier, Service, Service Type, and other filters relevant to the type of data asset. You can also search by deleted data assets.

Filter by the Type of Data Asset
The search results can be narrowed down by data assets such as Table, Topic, Dashboard, Pipeline, ML Model, Container, Glossary, or Tag.

Users can navigate to the Explore page for specific type of data assets and use the filter options relevant to that data assset to narrow down the search.
Filter by Database
When searching while you are in a database page, you can narrow down your search to within the database or to include the overall search results within OpenMetadata.

Filter based on Importance: Tiers
Using tiers, you can search for data based on importance.

Filter based on Importance: Usage
OpenMetadata captures usage profiles for tables during metadata/profiler ingestion. This helps to learn how other data consumers are using the tables. You can search by weekly usage, last updated status, as well as relevance.

Filter by Asset Owner
A team or a user can own the data asset in OpenMetadata. Users can filter data assets by the asset owner. With information on the data asset owners, you can direct your questions to the right person or team.

Discover Data through Association
OpenMetadata provides the links to the frequently joined tables and columns as measured by the data profiler. You can also discover assets through relationships based on data lineage.

Discover Assets through Relationships
OpenMetadata helps to locate assets of interest by tracing data lineage. You can view the upstream and downstream nodes to discover the sources of data and learn about the tables, pipelines, and more. The table and column descriptions help to decide if the data is helpful for your use case. Similarly, the pipeline description helps to uncover the transformation and more data of interest.

Advanced Search
Users can find data assets matching strict criteria by multiple parameters on metadata properties, using the syntax editor with and/or conditions. Advanced search in OpenMetadata supports Boolean operators and faceted queries to search for specific facets of your data. Separate advanced search options are available for Tables, Topics, Dashboards, Pipelines, ML Models, Containers, Glossary, and Tags.

Discover Data Evolution
By viewing lineage and metadata versioning, users can discover the data evolution of data assets.

Filter by Deleted Data Assets
Users can also search for the deleted data assets in OpenMetadata.
