Suggest Tags in Search

[Askir]

As a user I want to have existing tags suggested when I start typing into the searchbar In order to not have to guess with what my artifacts have been tagged

Elasticsearch provides a pretty useful API to implement search suggestions. We can use this feature to have the searchbar suggest auto completions when a user starts typing.

Acceptance Criteria

• [ ] When entering the first letter, the searchbar expands and suggests tags.
• [ ] These suggestions are updated continuously when the user adds more letters.
• [ ] After entering a space the suggestions start from scratch.
• [ ] The user can accept a suggestion by pressing tab (or clicking on it) which enters the suggestion into the searchbar.

I'd be implementing this by also indexing all our tags into elasticsearch in addition to our artifacts.

We could also think about refactoring the search as a whole and have it not work via a simple string but instead an array of "search tags". Or even support a more fleshed out query with something like
{tags: ["xyz"], author: "Jascha", date: "dd/mm/yy"}
