# Terms Matching Policies
This PR allows end users to customize matching term policies
## Todo
- [x] Update the API to return the number of pages and allow users to directly choose a page instead of computing an offset
- [x] Change generation of the query tree depending on the chosen settings https://github.com/meilisearch/milli/pull/598
## Small Documentation
### Default search query
**request**:
```sh
curl \
-X POST 'http://localhost:7700/indexes/movies/search' \
-H 'Content-Type: application/json' \
--data-binary '{ "q": "doctor of tokio" }'
```
**result**:
```json
{
"hits":[...],
"estimatedTotalHits":32,
"query":"doctor of tokio",
"limit":20,
"offset":0,
"processingTimeMs":7
}
```
The default behavior doesn't change with the current Meilisearch behavior:
If we don't have enough documents to fit the requested limit, we remove the query words from the last to the first typed word.
## Search query with `optionalWords` parameter
**request**:
```sh
curl \
-X POST 'http://localhost:7700/indexes/movies/search' \
-H 'Content-Type: application/json' \
--data-binary '{ "q": "doctor of tokio", "matchingStrategy": "all"}'
```
**result**:
```json
{
"hits":[...],
"estimatedTotalHits":1,
"query":"doctor of tokio",
"limit":20,
"offset":0,
"processingTimeMs":7
}
```
### allowed `matchingStrategy` values
#### `last`
The default behavior, If we don't have enough documents to fit the requested limit, we remove the query words from the last to the first typed word.
#### `all`
No word will be removed, If we don't have enough documents to fit the requested limit, we return the number of documents we found.

2689: Use mimalloc as the global allocator r=Kerollmops a=loiclec
milli has switched its global allocator to mimalloc already, and we have seen some performance gains as a result. Furthermore, we can use mimalloc as the global allocator on all platforms whereas jemalloc was only activated on Linux.
This PR brings mimalloc to Meilisearch as well.
2690: Add LTO and codegen-units=1 to release compile options r=Kerollmops a=loiclec
This PR brings Meilisearch's release compile options in line with milli (see https://github.com/meilisearch/milli/pull/606 ).
Adding LTO and codegen=units=1 will make compile times longer, but they also speed up the final binary significantly.

598: Matching query terms policy r=Kerollmops a=ManyTheFish
## Summary
Implement several optional words strategy.
## Content
Replace `optional_words` boolean with an enum containing several term matching strategies:
```rust
pub enum TermsMatchingStrategy {
// remove last word first
Last,
// remove first word first
First,
// remove more frequent word first
Frequency,
// remove smallest word first
Size,
// only one of the word is mandatory
Any,
// all words are mandatory
All,
}
```
All strategies implemented during the prototype are kept, but only `Last` and `All` will be published by Meilisearch in the `v0.29.0` release.
