Question

1. Briefly

I don't find, how I can mass replace string in multiple answers, questions and titles of questions of any Stack Exchange site.

2. Example

For example, I want to replace incorrect form of a word консоле to correct form консоли. In Russian Stack Overflow at the time of writing this post we have 278 results for консоле. It would be nice, if would be possible mass find and replace, even if regular expressions will not supported.

4. Notes

1. Yes, I understand, that before mass edits I need to ask Russian Stack Overflow community in Meta.
2. In Russian we don't have word or form of a word консоле. In several cases word консоль have a form консоли.
