[Photon] Next steps

[Christoph Lingg [mobil]]

I'll have a look on the plugin. For testing purposes I disabled tf/idf by changing the scoring method to replace (instead of multiply). Results were good but maybe I is not that, anyway I need a closer look on it.

I will work on a fuzzyless version next week then and add German test cases step by step. Would be helpful if I can get your advice when I need some help. Maybe that's possible?

If it is tricky and complex to summarise  fuzzy and fuzzless results in one es query, maybe it is worth to try an alternative approach that came up in my mind: we can first query without fuzzy then with fuzzy and merge both results to a final result list. Nonfuzzy results in first, third, fifth place whist fuzzy results in second, fourth ... I'll give it a try. Same could be done with location bias.

I would like to join you that weekend and it would definitely make sense, but exactly this weekend is difficult for me ;-(
