Add slop to quoted bare words

[saroh]

Following #1393
The fact that phrase queries are tokenized does not make this ideal TBH. It'd probably be better to have delimiters in the query language for a non tokenized string and have a slop param for it.

It is too dangerous to add if it is not soemthing we can disable via conf.

It is very easy to craft a fuzzy query that is very expensive, so any service with tantivy in prod would be vulnerable.

@fulmicoton yeah I'm closing this, imo it requires a little bit of design, we can't both tokenize and not tokenize within "".
