Based on the knowledge sources, Elementary Data doesn't currently support using multiple dbt selectors with the "+" operator syntax in its visualizer like you can in dbt-docs. There is an open feature request on GitHub specifically asking for this functionality. The issue titled "Add flexibility to Elementary Report with select exclude options to Lineage Graph" mentions that users would like to have the ability to use dbt syntax with unions, intersections, and graph operators like "@" and "+" in the Elementary Lineage view, similar to how it works in dbt-docs [GitHub Issue #1293](https://github.com/elementary-data/elementary/issues/1293). A GitHub collaborator responded to this issue noting that they've made significant changes to the lineage screen with various filtering options, though not with the exact dbt syntax but with a different UX. More recently, an Elementary team member commented that they're "actively working on improving this and adding filters to the Lineage" and will update once it's released. For now, you can use the existing search and filter functionality in the Elementary UI, which includes support for regular expressions in the search bar as mentioned in a closed GitHub issue [GitHub Issue #468](https://github.com/elementary-data/elementary/issues/468). If you need to run specific selections for monitoring or reporting via the CLI, Elementary does support some selection syntax, though it's not identical to dbt's. For CLI commands, you can use

--select

with various filters like

resource_types

,

tags

, and

statuses

. I hope this helps! The feature you're looking for appears to be in the works but isn't available yet.
