[FEATURE] Allow string search query for replace operator

[rhazn]

          This would be stronger as Regex OR string (so you could do `"Example" replace "ample" with "sample"` which is easier for non-programmers because you do not need to know regexes). I would like to add that in a follow up task if it is possible to do.
