DataErai’s search lets you find assets by combining simple conditions into a precise query. You build a query from clauses, and combine them with AND, OR, and NOT.

​
Clause types

ClauseFinds assets by
TextA free-text search across the asset.
TagA tag applied to the asset.
CreatorWho created the asset.
CollectionMembership in a specific collection.
IDA specific asset identifier.
MetadataA structured metadata field, using an operator and value.

​
Metadata conditions

Metadata clauses match on a field path with an operator and (for most operators) a value. The operators available depend on the field’s type:
OperatorMeaningTypes
= / ≠Equals / does not equalNumerical, string, boolean
> ≥ < ≤Numeric comparisonsNumerical
containsText contains a substringString
exists / not existsThe field is present / absentAll
contains item / does not contain itemAn array includes / excludes a valueArray
Extracted metadata and the metadata you add yourself are both searchable this way — for example, find every XRD scan with a specific anode material, or every asset missing a required field.

​
Combine conditions

Add multiple clauses and join them with AND (all must match), OR (any may match), or NOT (exclude matches) to express exactly what you’re looking for.
