Searching a string in eclipse workspace
eclipse
Solution
At the top level menus, select 'Search' -> 'File Search' Then near the bottom (in the scope) there is a choice to select the entire workspace.
For your "File search has encountered a problem", you need to refresh the files in your workspace, in the Project/Package Explorer, right click and select "Refresh" at any level (project, folder, file). This will sync your workspace with the underlying file system and prevent the problem.
Problem
How to search for a string in the complete eclipse workspace? I was not able to locate a text in the eclipse workspace however I could not find the specified string in the workspace.
