The Search Results panel is designed to only show one line per match (even if you do a search expression that matches text that crosses over lines, it will only show the first line of the match). There isn’t a way to increase context.

Support for multiple keywords would be an additional plus.

The existing regular expression (regex) feature already handles that.

• Find What = \b(George|Gracie|whale)\b
  • the \b matches “word boundary” so it would match George but not Georgene, etc.
  • the (...) makes a group - without this logical group, the \b would have to be repeated at the beginning and end of each word, like \bGeorge\b|\bGracie\b|\bwhale\b
  • the | means “OR”
  • translated to english, this Find What means “match a boundary, then George or Gracie or whale, then another boundary”
• Match Case = off
• Search Mode = Regular Expression
• . matches newline = off
