4631: Split the field id map from the weight of each fields r=Kerollmops a=irevoire
# Pull Request
## Related issue
Fixes https://github.com/meilisearch/meilisearch/issues/4484
## What does this PR do?
- Make the (internal) searchable fields database always contain the searchable fields (instead of None when the user-defined searchable fields were not defined)
- Introduce a new « fieldids_weights_map » that does the mapping between a fieldId and its Weight
- Ensure that when two searchable fields are swapped, the field ID map doesn't change anymore (and thus, doesn't re-index)
- Uses the weight instead of the order of the searchable fields in the attribute ranking rule at search time
- When no searchable attributes are defined, make all their weights equal to zero
- When a field is declared as searchable and contains nested fields, all its subfields share the same weight
## Impact on relevancy
### When no searchable attributes are declared
When no searchable attributes are declared, all the fields have the same importance instead of randomly giving more importance to the field we've encountered « the most early » in the life of the index.
This means that before this PR, send the following json:
```json
[
{ "id": 0, "name": "kefir", "color": "white" },
{ "id": 1, "name": "white", "last name": "spirit" }
]
```
Would make the field `name` more important than the field `color` or `last name`.
This means that searching for `white` would make the document `1` automatically higher ranked than the document `0`.
After this PR, all the fields have the same weight, and none are considered more important than others.
### When a nested field is made searchable
The second behavior change that happened with this PR is in the case you're sending this document, for example:
```json
{
"id": 0,
"name": "tamo",
"doggo": {
"name": "kefir",
"surname": "le kef"
},
"catto": "gromez"
}
```
Previously, defining the searchable attributes as: `["tamo", "doggo", "catto"]` was actually defining the « real » searchable attributes in the engine as: `["tamo", "doggo", "catto", "doggo.name", "doggo.surname"]`, which means that `doggo.name` and `doggo.surname` were _NOT_ where the user expected them and had completely different weights than `doggo`.
In this PR all the weights have been unified, and the « real » searchable fields look like this:
```json
[ "tamo", "doggo", "doggo.name", "doggo.surname", "catto"]
^^^^ ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^ ^^^^^
Weight 0 Weight 1 Weight 2

4619: Use http path pattern instead of full path in metrics r=irevoire a=gh2k
# Pull Request
## Related issue
Fixes#3983
## What does this PR do?
- This records only the HTTP pattern in metrics instead of the full path
An alternative solution was proposed in #4145, but this doesn't really fix the root cause of the issue. The problem I'm experiencing at my end is that by using the full path, the number of labels is far too high to be useful. It is normal practice to use the path with variable placeholders, instead of the fully-expanded path.
The example given in the ticket was endpoints under `/tasks`, but this can also be a very significant problem under `/indexes/{index-uid}/documents`. e.g.:
<img width="1510" alt="Screenshot 2024-05-03 at 12 14 36" src="https://github.com/meilisearch/meilisearch/assets/6530014/1df2ec19-5f69-4164-90d2-f65c59f9b544">
This patch replaces the fully-expanded path with the matched pattern.
The linked PR also mentions paths under other routes, e.g. `/static`, but this feels like a separate concern and these can be stripped out at the Prometheus end by filters if they are unwanted. The most important thing is to make the paths usable so that we can still get stats on e.g. the number of document deletes we see.
