Improve search usability

Is your feature request related to a problem? Please describe.
As a user I want to find relevant information, when using the search functionality

Describe the solution you'd like

• new Feature to catch spelling errors, by adding a "did you mean" feature. I think this would be nice for the user experience and also quite helpful when entering long/complex words in a language a user is not very well speaking.
• Feedback from Regensburg: In Regensburg, they have keywords on individual pages so that the pages can be found more easily using the search function. Now he had the idea of possibly creating a portfolio of keywords on the pages, allowing users to select from these keywords and also add their own. The same could be done for the search function as well. See more details for this here: https://tasks.tuerantuer.org/projects/service/work_packages/3722/activity

Describe alternatives you've considered

Additional context
We are thinking of added a automatic feedback to cities, if users enters something to the search and nothing is found. This feature may be result in a lot of feedback of typos, so we thought about the improvments above.

Just to add here - the second point with the feedback from Regensburg is up for discussion and would need implementation in the CMS as well. The question is what you think about this idea and also whether maybe the "did you mean" function would suffice. Having to add keywords would also increase the work of municipalities (unless we can employ KI or some other intelligent script that can identify possible keywords based on other words in the content).
