What is the proper syntax to use for this search please?

I've tried surrounding the text below with and "" but just get errors of:

  • Discover: Expected ":", "<", "<=", ">", ">=", "and", "or", [\ \t\r\n] or end of input but "d" found.
  • Discover: Expected "*", "", [\ \t\r\n] or end of input but """ found.

search string:
echo 0 > /proc/sys/kernel/hung_task_timeout_secs" disables this message

I think the problem is the single " in your example line. Try removing that or escaping it.

The search bar uses lucene query syntax.
