Does App Search allow using custom tokenizers and stop words? How do I introduce new stop words to the indexer? Also, is there a way to see how the score is calculated, like a query analyzer? I'm new to App Search and Elasticsearch. As far as I understand, one of the motivations to use App Search should be to avoid using custom stuff but still there might be some cases where it comes handy. A query analyzer would help a lot as well. Thanks.

Hello,

We don't allow customization of stop words or tokenizers currently. There also isn't a granular way to break down scoring, though we do provide a realtime view as you make changes in Relevance Tuning. We're always happy to hear feedback and feature requests!

Best,  
Quin
