Summary

• Primarily, it would be beneficial to allow the ability to search from "Description" field in Kanban view. 
• Ability to search for Partial word matches.
• Exact matches in Summary and Description should at least be consistent across views 
  • Kanban View
  • List View
  • Calendar View
  • Calendar View > Unscheduled tasks
  • Timeline View

Current Results

Description field text is not exposed to other features due to overall performance impact it can cause. As description field can be quite lengthy, its not available by design and every view has different type of implementations.

Expected Results 

Please provide an ability to improve the search mechanism as requested especially the Description field in Kanban and other requests as defined in the summary

Workaround:

Check whether Issue Navigator search can be utilized by JQL searches for e.g. 

projectType=business and text ~ "word"
