# Search for concepts with concrete domain values by ECL query

{% hint style="success" %}
**Finding concepts with concrete domain values**\


Existing concepts containing attributes with concrete domain values can be found by searching with an ECL query containing a concrete domain value refinement:\


For instance, this ECL query returns all concepts that have an attribute with the concrete value 12.5:\
`* : * = #12.5`\


This query returns all concepts that have an attribute with a concrete value greater than zero:\
`* : * > #0`
