309: Sort at query time r=Kerollmops a=Kerollmops
This PR:
- Makes the `Asc/Desc` criteria work with strings too, it first returns documents ordered by numbers then by strings, and finally the documents that can't be ordered. Note that it is lexicographically ordered and not ordered by character, which means that it doesn't know about wide and short characters i.e. `a`, `丹`, `▲`.
- Changes the syntax for the `Asc/Desc` criterion by now using a colon to separate the name and the order i.e. `title:asc`, `price:desc`.
- Add the `Sort` criterion at the third position in the ranking rules by default.
- Add the `sort_criteria` method to the `Search` builder struct to let the users define the `Asc/Desc` sortable attributes they want to use at query time. Note that we need to check that the fields are registered in the sortable attributes before performing the search.
- Introduce a new `InvalidSortableAttribute` user error that is raised when the sort criteria declared at query time are not part of the sortable attributes.
- `@ManyTheFish` introduced integration tests for the dynamic Sort criterion.
Fixes#305.

302: Update milli to v0.9.0 r=curquiza a=curquiza
Updating the minor and not patch since #300 seems to be breaking: it involves a re-indexation to get the fix, so it involves an additional step from the users, not only downloading the latest version.

300: Fix prefix level position docids database r=curquiza a=ManyTheFish
The prefix search was inverted when we generated the DB.
Instead of searching if word had a prefix in prefix fst,
we were searching if the word was a prefix of a prefix contained in the prefix fst.
The indexer, now, iterate over prefix contained in the fst
and search them by prefix in the word-level-position-docids database,
aggregating matches in a sorter.
Fix#299

291: Fix a bug about zero bytes in the inputs r=irevoire a=Kerollmops
Ok, good news, after a little session of debugging with `@irevoire` we found out that the bug seems to be related to zeroes in the input update. The engine wasn't designed to accept those. The chosen solution is to update the tokenizer to remove those zeroes. We are waiting on https://github.com/meilisearch/tokenizer/pull/52 to be merged and a new version to be released.
It is not an undefined behavior, I repeat: it is a "normal" bug 🎉👏
----
This PR tries to fix a bug where we use LMDB in the wrong way, leading to panic due to an undefined behavior on the Rust side. I thought [we fixed it in a previous PR](https://github.com/meilisearch/milli/pull/264) but we found out that _a similar_ bug was still present. `@bb` found a way to trigger this bug and helped us find the origin of it.
As I don't have a minimal reproducible example of this bug I bet on the unsafe `put_current` calls when we index new documents as the bug was trigger after a big indexation on a clean database, thus not triggering a deletion update. I only replaced the unsafe `put_current` with two safe calls to `get`/`put`.
I hope it helps and fixes the bug, only `@bb` can help us check that. I am not even sure how I can create a custom Docker image and expose it for testing purposes.

269: Fix bug when inserting previously deleted documents r=Kerollmops a=Kerollmops
This PR fixes#268.
The issue was in the `ExternalDocumentsIds` implementation in the specific case that an external document id was in the soft map marked as deleted.
The bug was due to a wrong assumption on my side about how the FST unions were returning the `IndexedValue`s, I thought the values returned in an array were in the same order as the FSTs given to the `OpBuilder` but in fact, [the `IndexedValue`'s `index` field was here to indicate from which FST the values were coming from](https://docs.rs/fst/0.4.7/fst/map/struct.IndexedValue.html).
271: Remove the roaring operation functions warnings r=Kerollmops a=Kerollmops
In this PR we are just replacing the usages of the roaring operations function by the new operators. This removes a lot of warnings.
Co-authored-by: Kerollmops <clement@meilisearch.com>
It is undefined behavior to keep a reference to the database while
modifying it, we were keeping references in the database and also
feeding the heed put_current methods with keys referenced inside
the database itself.

222: Move the `UpdateStore` into the http-ui crate r=Kerollmops a=Kerollmops
We no more need to have the `UpdateStore` inside of the mill crate as this is the job of the caller to stack the updates and sequentially give them to milli.

220: Make hard separators split phrase query r=Kerollmops a=ManyTheFish
hard separators will now split a phrase query as two sequential phrases (double-quoted strings):
the query `"Radioactive (Imagine Dragons)"` would be considered equivalent to `"Radioactive" "Imagine Dragons"` which as the little disadvantage of not keeping the order of the two (or more) separate phrases.
