407: Update version for the next release (v0.20.0) r=curquiza a=curquiza
Breaking because of #405 and #406
Co-authored-by: Clémentine Urquizar <clementine@meilisearch.com>
402: Optimize document transform r=MarinPostma a=MarinPostma
This pr optimizes the transform of documents additions in the obkv format. Instead on accepting any serializable objects, we instead treat json and CSV specifically:
- For json, we build a serde `Visitor`, that transform the json straight into obkv without intermediate representation.
- For csv, we directly write the lines in the obkv, applying other optimization as well.

384: Replace memmap with memmap2 r=Kerollmops a=palfrey
[memmap is unmaintained](https://rustsec.org/advisories/RUSTSEC-2020-0077.html) and needs replacing. memmap2 is a drop-in replacement fork that's well maintained. Note that the version numbers got reset on fork, hence the lower values.

388: fix primary key inference r=MarinPostma a=MarinPostma
The primary key is was infered from a hashtable index of the field. For this reason the order in which the fields were interated upon was not deterministic, and the primary key was chosed ffrom the first field containing "id".
This fix sorts the the index by field_id when infering the primary key.
Co-authored-by: mpostma <postma.marin@protonmail.com>
Instead of using an arbitrary limit we encode the absolute position in a u32
using one strong u16 for the field id and a weak u16 for the relative position in the attribute.
386: fix obkv document r=curquiza a=MarinPostma
When serializing a document, the serializer resolved the field_id of the current field and immediately added it to the obkv document under construction. The issue with that is that obkv expects the fields to be inserted in order, and when a document with out of order fields was added, obkv failed to insert the field.
The current fix first resolves each field_id, and adds all the fields to a temporary `BTreeMap`, until `end` is called on the map serializer, where all the fields are added to the obkv at once, and in order.

Latitude are not supposed to go beyound 90 degrees or below -90.
The same goes for longitude with 180 or -180.
This was badly implemented in the filters, and was not implemented for the AscDesc rules.

372: Fix Meilisearch 1714 r=Kerollmops a=ManyTheFish
The bug comes from the typo tolerance, to know how many typos are accepted we were counting bytes instead of characters in a word.
On Chinese Script characters, we were allowing 2 typos on 3 characters words.
We are now counting the number of char instead of counting bytes to assign the typo tolerance.

360: Update version for the next release (v0.14.0) r=Kerollmops a=curquiza
Release containing the geosearch, cf #322
Co-authored-by: Clémentine Urquizar <clementine@meilisearch.com>
322: Geosearch r=ManyTheFish a=irevoire
This PR introduces [basic geo-search functionalities](https://github.com/meilisearch/specifications/pull/59), it makes the engine able to index, filter and, sort by geo-point. We decided to use [the rstar library](https://docs.rs/rstar) and to save the points in [an RTree](https://docs.rs/rstar/0.9.1/rstar/struct.RTree.html) that we de/serialize in the index database [by using serde](https://serde.rs/) with [bincode](https://docs.rs/bincode). This is not an efficient way to query this tree as it will consume a lot of CPU and memory when a search is made, but at least it is an easy first way to do so.
### What we will have to do on the indexing part:
- [x] Index the `_geo` fields from the documents.
- [x] Create a new module with an extractor in the `extract` module that takes the `obkv_documents` and retrieves the latitude and longitude coordinates, outputting them in a `grenad::Reader` for further process.
- [x] Call the extractor in the `extract::extract_documents_data` function and send the result to the `TypedChunk` module.
- [x] Get the `grenad::Reader` in the `typed_chunk::write_typed_chunk_into_index` function and store all the points in the `rtree`
- [x] Delete the documents from the `RTree` when deleting documents from the database. All this can be done in the `delete_documents.rs` file by getting the data structure and removing the points from it, inserting it back after the modification.
- [x] Clearing the `RTree` entirely when we clear the documents from the database, everything happens in the `clear_documents.rs` file.
- [x] save a Roaring bitmap of all documents containing the `_geo` field
### What we will have to do on the query part:
- [x] Filter the documents at a certain distance around a point, this is done by [collecting the documents from the searched point](https://docs.rs/rstar/0.9.1/rstar/struct.RTree.html#method.nearest_neighbor_iter) while they are in range.
- [x] We must introduce new `geoLowerThan` and `geoGreaterThan` variants to the `Operator` filter enum.
- [x] Implement the `negative` method on both variants where the `geoGreaterThan` variant is implemented by executing the `geoLowerThan` and removing the results found from the whole list of geo faceted documents.
- [x] Add the `_geoRadius` function in the pest parser.
- [x] Introduce a `_geo` ascending ranking function that takes a point in parameter, ~~this function must keep the iterator on the `RTree` and make it peekable~~ This was not possible for now, we had to collect the whole iterator. Only the documents that are part of the candidates must be sent too!
- [x] This ascending ranking rule will only be active if the search is set up with the `_geoPoint` parameter that indicates the center point of the ascending ranking rule.
-----------
- On Meilisearch part: We must introduce a new concept, returning the documents with a new `_geoDistance` field when it passed by the `_geo` ranking rule, this has never been done before. We could maybe just do it afterward when the documents have been retrieved from the database, computing the distance from the `_geoPoint` and all of the documents to be returned.

342: Let the caller decide what kind of error they want to returns when parsing `AscDesc` r=Kerollmops a=irevoire
This is one possible fix for #339
We would then need to patch these lines https://github.com/meilisearch/MeiliSearch/blob/main/meilisearch-http/src/index/search.rs#L110-L114 to return the error we want.
Another solution would be to add a parameter to the `from_str` to specify which context we are in.

344: Move the sort ranking rule before the exactness ranking rule r=ManyTheFish a=Kerollmops
This PR moves the sort ranking rule at the 5th position by default, right before the exactness one.
Co-authored-by: Kerollmops <clement@meilisearch.com>
341: Throw a query time error when a sort parameter is used but the sort ranking rule is missing r=Kerollmops a=Kerollmops
This PR makes the engine throw an error for when the ranking rules don't contain the `sort` rule, the `sortable_fields` are correctly set but the user tries to use the `sort` query parameter. Doing so will have no effect on the returned documents so we preferred returning an error to help debug this.
That's breaking on the MeiliSearch side as we added a new variant to the `UserError` enum.

308: Implement a better parallel indexer r=Kerollmops a=ManyTheFish
Rewrite the indexer:
- enhance memory consumption control
- optimize parallelism using rayon and crossbeam channel
- factorize the different parts and make new DB implementation easier
- optimize and fix prefix databases
Co-authored-by: many <maxime@meilisearch.com>
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.

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).
