[FR] Add a comprehensive search feature to archive

[JeS24]

Title-text. To any netizen, it should be obvious why a search feature would be helpful.

The more interesting part would be how to implement such a feature. OCR would undoubtedly see some use here, but it will require sufficiently "clean" inputs. Another component that will require some thought is the data structure used to store the (crawled) data. Should be an interesting project. For something fancy, one might want to look into fuzzy finders or knowledge graphs.

As a start, even a rudimentary string-matching search function helps. SDG can improve it as time goes on.

@ maintainers Feel free to edit this text to add more details or clarifications, as needed.
