458: Nested fields r=Kerollmops a=irevoire
For the following document:
```json
{
"id": 1,
"person": {
"name": "tamo",
"age": 25,
}
}
```
Suppose the user sets `person` as a filterable attribute. We need to store `person` in the filterable _obviously_. But we also need to keep track of `person.name` and `person.age` somewhere.
That’s where I changed a little bit the logic of the engine.
Currently, we have a function called `faceted_field` that returns the union of the filterable and sortable.
I renamed this function in `user_defined_faceted_field`. And now, when we finish indexing documents, we look at all the fields and see if they « match » a `user_defined_faceted_field`.
So in our case:
- does `id` match `person`: 🔴
- does `person.name` match `person`: 🟢
- does `person.age` match `person`: 🟢
And thus, we insert in the database the following faceted fields: `person, person.name, person.age`.
The good thing about that solution is that we generate everything during the indexing phase, and then during the search, we can access our field without recomputing too much globbing.
-----
Now the bad thing is that I had to create a new db.
And if that was only one db, that would be ok, but actually, I need to do the same for the:
- Displayed attributes
- Attributes to retrieve
- Attributes to highlight
- Attribute to crop
`@Kerollmops`
Do you think there is a better way to do it?
Apart from all the code, can we have a problem because we have too many dbs?

474: Disable typos on exact word r=MarinPostma a=MarinPostma
This PR introduces the `exact_word` setting to disable typo tolerance on custom words.
If a user query contains a word from `exact_words`, no typo derivation will be made for that particular word.
I have chosen to store the words in a FST, to save on deserialization, and allow for fast lookups.
I had some trouble with the `serde` module, and had to rename it `serde_impl`.
## steps:
- [x] introduce new settings to register words to disable typos on
- [x] in `typos`, return exact match is the current word is part of the word to disable typos for.
- [x] update `Context` to return the exact words dictionary.
- [x] merge #473

473: set minimum word len for typos r=MarinPostma a=MarinPostma
this PR allows the configuration on the minimum word length for typos.
The default values are the same as previously.
## steps
- [x] introduce settings for the minimum word length for 1 and 2 typos
- [x] update the settings update flow to set this setting
- [x] create a structure `TypoConfig` to configure typo tolerance in the query builder
- [x] in `typo`, use the configuration to create the appropriate query tree node.
- [x] extend `Context` to return the setting for minimum word length for typos
- [x] return correct error message for wrong settings.
- [x] merge #469
