@Grodou amazing work! I left some comments, mostly about namings and redundant code, please take a look Thank you very much for contribution

[Grodou]

@sealedtx Thank you! It was no piece of cake :) I'll make some changes and provide a better version soon.

[Grodou]

There are 3 new kinds of item renderers, they are all:

• providing one or more search paths, each can lead to another search action
• (afaik) on the "initial" result page only, not on continuations
• (afaik) unique: one occurence max per result

They're not really suitable as items, they are QueryElements. Not the best name ever.

As results may change from a moment to few seconds later, advanced tests are tricky. Especially for refinements, sometimes there are, sometimes not. The related test worked for some times, but is not reliable, it is commented for now.

@Grodou I believe lot of research was done to implement this feature, great job! Thank you! Please, ping me, when you finish and PR will be ready to merge

[Grodou]

Just a last new feature: force exact query to avoid auto-correction. In ParserImpl.parseSearchResultElement, there's still a console print for unknown element types. @sealedtx Ready to merge for me, I won't investigate any further for now. I'm glad I could help. Cheers
