What issue are you seeing?

Task search does not find text from recent tasks.
If the intent of that feature is to only find text in the first prompt, or in the displayed name of the task, that's not clear.

First image of search result shows the first and only occurrence of word "browser" is in a task from a month ago.

This image confirms two tasks processed within the last two days.

These images show the word "browser" in multiple contexts (prompt, response, code, link) in those two recent tasks. Conclusion: the search is not finding the text in any of these contexts.

What steps can reproduce the bug?

In extension, side pane, open Task History to the Search Recent Tasks text box. Ensure All Tasks are in view.
Enter text which is known to be present in recent tasks. Some tasks may be displayed, not all with the text.

Text is not found in prompts, links, code, or plain text responses.

What is the expected behavior?

Search should find text, no matter where it is in prompts or responses, from all tasks that are selected (all, cloud, local).

Additional information

VSCode version indicated is v0.4.71. I'm running a lower version to avoid a later bug. But the issue is present in other versions - please don't respond with "upgrade and re-confirm".
