3749: Fix back: sort error message r=ManyTheFish a=ManyTheFish
This PR reintroduces the error message modified in https://github.com/meilisearch/milli/pull/375.
However, this added double-quotes around `sort` in the message. I don't think another message contains double-quotes, so I have added a separate commit replacing the double-quotes with back-ticks, which seems more consistent with the other error messages, this last change can be reverted easily.
## Detailed changes
#### v1.2-rc0
```
The sort ranking rule must be specified in the ranking rules settings to use the sort parameter at search time.
```
#### [Reintroduce fix (previous and expected behavior)](23d1c86825)
```
You must specify where "sort" is listed in the rankingRules setting to use the sort parameter at search time
```
#### [Replace double-quotes with back-ticks (my suggestion)](4d691d071a)
```
You must specify where `sort` is listed in the rankingRules setting to use the sort parameter at search time

3651: Use the writemap flag to reduce the memory usage r=irevoire a=Kerollmops
This draft PR is showing some stats about the memory usage of Meilisearch when [the LMDB `MDB_WRITEMAP` flag](3947014aed/libraries/liblmdb/lmdb.h (L573-L581)) is enabled and when it is not. As you can see there is a reduction of about 50% of the memory usage pick. The dataset used was [the Wikipedia one](https://www.notion.so/meilisearch/Wikipedia-8b1486e4b17547c5bda485d2d97767a0) with the first 30 000 first CSV documents without settings. This PR depends on https://github.com/meilisearch/heed/pull/168.
I just [opened a discussion](https://github.com/meilisearch/product/discussions/652) for people to understand the tradeoffs and give their feedback.
- [x] Create an experiment flag `--experimental-reduce-indexing-memory-usage`.
- [x] Add it to the config file.
- [x] Explain the tradeoff and copy/link the LMDB documentation in the help message.
- [x] Add analytics about the experimental flag.
- [x] Document that this flag cannot be used on Windows, ~~or hide it~~.

<summary>The command I used to run the tests</summary>
#### Sign the binary to be able to use Instruments / xcrun
```sh
codesign -s - -f --entitlements ~/ent.plist target/release/meilisearch
```
where `ent.plist` contains:
```xml

```
#### Run Meilisearch in measure-mode
```sh
xcrun xctrace record --template 'Allocations' --launch -- target/release/meilisearch --max-indexing-memory 0MiB
```
#### Send the wiki dataset available on notion.so / Public
```sh
for f in 0.csv 15000.csv; do echo sending $f; xh 'localhost:7700/indexes/wiki/documents' 'content-type:text/csv' `@$f;` done
```
#### Wait for the task to finish
```sh
watch --color xh --pretty all 'localhost:7700/tasks?statuses=processing'
```
</details>
Keep in mind that I tested that with the Instruments Apple tools on an iMac 5k 2019. More benchmarks must be done, especially on the indexation speed, as the flag is told to slow down writing into databases bigger that the amount of memory.
On the left Meilisearch is running without the flag. On the right, it is running with the flag.

3687: Allow to disable specialized tokenizations (again) r=Kerollmops a=jirutka
In PR #2773, I added the `chinese`, `hebrew`, `japanese` and `thai` feature flags to allow melisearch to be built without huge specialed tokenizations that took up 90% of the melisearch binary size. Unfortunately, due to some recent changes, this doesn't work anymore. The problem lies in excessive use of the `default` feature flag, which infects the dependency graph.
Instead of adding `default-features = false` here and there, it's easier and more future-proof to not declare `default` in `milli` and `meilisearch-types`. I've renamed it to `all-tokenizers`, which also makes it a bit clearer what it's about.

3570: Get documents by filter r=irevoire a=dureuill
# Pull Request
## Related issue
Associated spec: https://github.com/meilisearch/specifications/pull/234
None really, this is more of an extension of #3477: since after this issue we'll be able to delete documents by filter, it makes sense to also be able to get documents by filter.
## What does this PR do?
### User standpoint
- Add a new `filter` URL parameter to `GET /indexes/{:indexUid}/documents` and a new `POST /indexes/{:indexUid}/documents/fetch` route with the same `offset, limit, fields, filter`
### Implementation standpoint
- Add a new `Index::iter_documents` method to iterate on a set of documents rather than return a vector of these documents.
- Rewrite the other `Index::*documents` methods to use the new `Index::iter_documents` method.

# Draft status
- [ ] Route naming: having one route be `GET /indexes/{:indexUid}/documents` and the other `POST /indexes/{:indexUid}/documents/fetch` is suboptimal (also, technically a breaking change for documents with `fetch` as uid?), but `POST /indexes/{:indexUid}/documents` is already used to insert documents.

3550: Delete documents by filter r=irevoire a=dureuill
# Prototype `prototype-delete-by-filter-0`
Usage:
A new route is available under `POST /indexes/{index_uid}/documents/delete` that allows you to delete your documents by filter.
The expected payload looks like that:
```json
{
"filter": "doggo = bernese",
}
```
It'll then enqueue a task in your task queue that'll delete all the documents matching this filter once it's processed.
Here is an example of the associated details;
```json
"details": {
"deletedDocuments": 53,
"originalFilter": "\"doggo = bernese\""
}
```

## What does this PR do?
### User standpoint
- Modifies the `/indexes/{:indexUid}/documents/delete-batch` route to accept either the existing array of documents ids, or a JSON object with a `filter` field representing a filter to apply. If that latter variant is used, any document matching the filter will be deleted.
### Implementation standpoint
- (processing time version) Adds a new BatchKind that is not autobatchable and that performs the delete by filter
- Reuse the `documentDeletion` task with a new `originalFilter` detail that replaces the `providedIds` detail.
## Example

## Draft status
- [ ] Error handling
- [ ] Analytics
- [ ] Do we want to reuse the `delete-batch` route in this way, or create a new route instead?
- [ ] Should the filter be applied at request time or when the deletion task is processed?
- The first commit in this PR applies the filter at request time, meaning that even if a document is modified in a way that no longer matches the filter in a later update, it will be deleted as long as the deletion task is processed after that update.
- The other commits in this PR apply the filter only when the asynchronous deletion task is processed, meaning that documents that match the filter at processing time are deleted even if they didn't match the filter at request time.
- [ ] If keeping the filter at request time, find a more elegant way to recover the user document ids from the internal document ids. The current way implemented in the first commit of this PR involves getting all the documents matching the filter, looking for the value of their primary key, and turning it into a string by copy-pasting routines found in milli...
- [ ] Security consideration, if any
- [ ] Fix the tests (but waiting until product questions are resolved)
- [ ] Add delete by filter specific tests

3693: Implement the auto deletion of tasks r=dureuill a=irevoire
Fixes https://github.com/meilisearch/meilisearch/issues/3622
This PR should be the definite fix for #3622.
It adds a limit (1M) to the maximum number of tasks the task queue can hold.
Once the task queue reaches this limit (1M of tasks are in the task queue, whatever their status is), meilisearch will schedule a task deletion that tries to delete the oldest 100k tasks.
If meilisearch can't delete 100k tasks because some of them are not yet finished, it will delete as many tasks as possible.
Once the limit is reached, you're still able to register new tasks. The engine will only stop you from adding new tasks once [the other hard limit](https://github.com/meilisearch/meilisearch/pull/3659) of 10GiB of tasks is reached (that's between 5M and 15M of tasks depending on your workflow).
-------
Technically;
- We only try to schedule our task deletion when calling the tick function but before creating a new batch. This means we never enqueue a task we're not going to process ~right away.
- If our task deletion doesn't delete anything, we don't enqueue it and log a warn the user that the engine is not working properly
