Summary

• Jira seems to treat the underscore character to be identical to a space character.
• Search query for exact phrases using underscore return results as the same phrase using a space, for example:
  • Searching for text ~ "\"END_OF\"" returns: "End of" instead of the exact "End_of" (Jira is considering underscore as a regular space character);
• This behavior is true for sentences with multiple underscores as well

Steps to Reproduce

1. Navigate to Jira Advanced issue search (e.g. on GSAC);
2. Search for any phrase containing an Underscore (e.g. text ~ "\"END_OF\"");
3. Displayed results will include phrases with space between words instead of underscore (e.g. "End Of" instead of "End_of");
   • Tried the syntax variation: text ~ "\"END\\_OF\"", just to be sure that Jira would not consider underscore as a reserved character;

Expected Results

• Search results for exact phrase syntax should return the exact term searched (even if it includes an underscore);

Actual Results

• Jira is treating underscore the same as a space character, returning search results that use a space instead of an underscore between words, when using the "exact phrase" syntax.
