3913: Expose a Puffin server to profile the indexing process r=Kerollmops a=Kerollmops
This PR exposes a puffin HTTP server to expose the internal timing it takes to index documents, delete documents, or update the settings of an index.

## To be done
- [x] Move the puffin HTTP server under a feature flag.
- [x] Use [the `puffin::set_scopes_on` function](https://docs.rs/puffin/latest/puffin/fn.set_scopes_on.html) to toggle it (by using the feature directly).
When this function is called with `false`, [a call to `profile_scope!` talked 1-2ns](https://docs.rs/puffin/latest/puffin/fn.set_scopes_on.html).
- [x] Create a _PROFILING.md_ file explaining how to use it.
- [x] Explain that merging scopes on the interface is not always useful.
- [x] Add more info on the number of batched tasks (using the `puffin::profile_scope!` macro data).
- I added more info, but that's more continuous work when we consider we need more info here and there.
- [x] Clean up some scopes, and don't touch too much code to inject puffin.
- I am not sure that the _index_documents/mod.rs_ function is that complex with the addition of the scope.
- [x] Think about what we consider frames. One indexation operation or the wall program. When must we stop the frame, then?
- What we consider a frame is one single `IndexScheduler::tick` execution.
- We can change that later.

3932: Add UTM tracking to README r=gillian-meilisearch a=Strift
# Pull Request
Hi `@macraig` `@curquiza` 👋
## Related issue
N/A
## What does this PR do?
This PR adds UTM tracking to the links in the README.
It add UTM params to:
- links in the nav
- links to where2watch
- links in the Features section
- Docs & Getting started links (cc `@guimachiavelli)`
- links in the SDKs section
- links in the Advanced usage section
- links in the Telemetry section
- links in the Get in touch section
Additionally, this PR adds a link to the Meilisearch logo (there is currently none.)
## On the UTM pattern
All links in this PR use the new convention `@gmourier` and I agreed on:
- utm_campaign=oss
- utm_source=github
- utm_medium=meilisearch
- utm_content= where the link is in the page
It's worth considering updating the tracking link for the Cloud, which is the only one that doesn’t follow the new convention. It is currently using `utm_campaign=oss&utm_source=engine&utm_medium=meilisearch`.
Merging analytics from different UTMs is doable on Amplitude, but can't be done in Fathom. Plus, having two different conventions creates knowledge overhead, and is bound to result in corrupt analytics at some point. I suggest we change the Cloud UTM trackers too — the sooner we eat the frog, the better imo.

3866: Update charabia v0.8.0 r=dureuill a=ManyTheFish
# Pull Request
Update Charabia:
- enhance Japanese segmentation
- enhance Latin Tokenization
- words containing `_` are now properly segmented into several words
- brackets `{([])}` are no more considered as context separators so word separated by brackets are now considered near together for the proximity ranking rule
- fixes#3815
- fixes#3778
- fixes [product#151](https://github.com/meilisearch/product/discussions/151)
> Important note: now the float numbers are segmented around the `.` so `3.22` is segmented as [`3`, `.`, `22`] but the middle dot isn't considered as a hard separator, which means that if we search `3.22` we find documents containing `3.22`

3780: Be able to sort facet values by alpha or count r=dureuill a=Kerollmops
This PR introduces a new `sortFacetValuesBy` settings parameter to expose the facet distribution in either count or lexicographic/alpha order.
## Mini Spec of the `sortFacetValuesBy` Settings Parameter
This parameter can be set in the settings to change how the engine returns the facet values. There are two possible values to this parameter.
Please note that the current behavior changed a bit, and keys are returned in lexicographic order instead of undefined order. The previous order wasn't defined as we were using a `HashMap`, which returns entries in hash order (undefined), and we are now using an `IndexMap`, which returns them in insertion order (the order we actually want).
Also, note that there are performance issues when the dataset is enormous. Here are the timings of the engine running on my Macbook Pro M1 (16Go of RAM). [The dataset is 40 million songs file](https://www.notion.so/meilisearch/Songs-from-MusicBrainz-686e31b2bd3845898c7746f502a6e117), and the database size is about 50GiB. Even if you think 800ms is not that high, don't forget that the API is public, and anybody can ask for multiple facets in a single query.
| Search Kind | Get Facets | Max Values per Facet | Time for Alpha | Time for Count | Count but with #3788 |
|------------:|------------|----------------------|:--------------:|----------------|----------------------|
| Placeholder | genres | default (100) | 7ms | 187ms | 122ms |
| Placeholder | genres | 20 | 6ms | 124ms | 75ms |
| Placeholder | album | default (100) | 9ms | 808ms | 677ms |
| Placeholder | album | 20 | 8ms | 579ms | 446ms |
| Placeholder | artist | default (100) | 9ms | 462ms | 344ms |
| Placeholder | artist | 20 | 9ms | 341ms | 246ms |
### Order Values in Alphanumeric Order
This is the default one. Values will be returned by lexicographic order, ascending from A to Z.
```bash
# First, update the settings
curl 'localhost:7700/indexes/movies/settings/facetting' \
-H "Content-Type: application/json" \
-d '{ "sortFacetValuesBy": { "*": "alpha" } }'
# Then, ask for the facet distribution
curl 'localhost:7700/indexes/movies/search?facets=genres'
```
```json5
{
"hits": [
/* list of results */
],
"query": "",
"processingTimeMs": 0,
"limit": 20,
"offset": 0,
"estimatedTotalHits": 1000,
"facetDistribution": {
"genres": {
"Action": 3215,
"Adventure": 1972,
"Animation": 1577,
"Comedy": 5883,
"Crime": 1808,
// ...
}
},
"facetStats": {}
}
```
### Order Values in Count Order
Facet values are sorted by decreasing count. The count is the number of records containing this facet value in the query results.
```bash
# First, update the settings
curl 'localhost:7700/indexes/movies/settings/facetting' \
-H "Content-Type: application/json" \
-d '{ "sortFacetValuesBy": { "*": "count" } }'
# Then, ask for the facet distribution
curl 'localhost:7700/indexes/movies/search?facets=genres'
```
```json5
{
"hits": [
/* list of results */
],
"query": "",
"processingTimeMs": 0,
"limit": 20,
"offset": 0,
"estimatedTotalHits": 1000,
"facetDistribution": {
"genres": {
"Drama": 7337,
"Comedy": 5883,
"Action": 3215,
"Thriller": 3189,
"Romance": 2507,
// ...
}
},
"facetStats": {}
}
```
## Todo List
- [x] Add tests
- [x] Send analytics when a user change the `sortFacetValuesBy`
- [x] Create a prototype and announce it in https://github.com/meilisearch/product/discussions/519.
