Add new search dialog

Feature request

The search works pretty well in the map. It does not work well in the node explorer. When I search for something that is one folder or more below what I have expanded, I do not see what the search found. See this search for "model", which is inside analysis but also inside visualization/app/codecharta:

I looked around a bit and saw what IntelliJ or Spotlight do and I think we can improve search fundamentally.

Description

As an auditor, I want a new search dialog that clearly shows the search result.

I think the existing node explorer is not the perfect place for the search result, because the node explorer has the tree structure is not so helpful. I checked what IntelliJ does and I think searching for something should open a new dialog that shows only what is matched. It could look like this:

Depending on if the user clicks on a search result, the new dialog would then show either the old node explorer or select the search result in the node explorer:

What do you think?

Acceptance criteria

• Searching for something opens a new search dialog that shows what files are matched
  • in the map
  • not in the map, because it has no area metric
  • in flattened files
  • in excluded files
• Selecting something in the new dialog shows the old node explorer again with the element selected
• Pressing enter without selecting something shows the old node explorer again but indicates via color inside which folder the search result is

Assumptions & Exclusions

Development notes (optional Task Breakdown)

Open questions

No files, tests, or entry points are named in the issue. Start by locating the existing map and node-explorer search implementation, then trace how results are selected and displayed. Done means a dialog covers all listed result categories and returns to the node explorer with the specified selection or folder indication.
