In Axiom, if you enable properties in the tag picker list, search queries will look in both the tag name and the properties (like description). In the Excel Add-In, queries only look in the tag name field.

A lot of people have tags based on useless source system IDs (like PI001.PV) and haven't invested resources in building out a view yet. But a lot of them have description fields that come from the data source (like Oil Drum Pressure). It would be nice is search looked in properties in addition to tag name.
