For feature names and descriptions, we have standard naming conventions. It would be useful to filter using 'contains' for the name and other txt fields. This way you can filter things together and apply a tag or perform a bulk edit.
Thank you for the request. We currently have the ability to search features names. This can be done by selecting the filter for "Feature search." This would allow you to search the feature name and reference ID.
At this time, we do not have this functionality available for feature descriptions but we hope the Feature name search can help.
Based on the feature name search capability, we will mark this idea as Already exists. If the description capability is still of interest, please feel free to submit a follow-up idea.
