Great job! Your plugins and additions are really useful. You are on the right track and hope to see more and more useful tools from you!
I would like to add few comments may be useful for future development
- there was some efforts in the past to include fuzzy search (I mean here to get better results)
- a discussion here has some good points for improvement search results. @pmario has given some good hints there
- Searching in links with the word
searchbrings some good previous efforts
Thank you again for all your efforts.
