## Introduction
|
|
|
|
This repository contains the core engine used in [meilisearch].
|
|
|
|
It contains a library that can manage one and only one index. meilisearch
|
|
manages the multi-index itself. Milli is unable to store updates in a store:
|
|
it is the job of something else above and this is why it is only able
|
|
to process one update at a time.
|
|
|
|
This repository contains crates to quickly debug the engine:
|
|
- There are benchmarks located in the `benchmarks` crate.
|
|
- The `http-ui` crate is a simple HTTP dashboard to tests the features like for real!
|
|
- The `infos` crate is used to dump the internal data-structure and ensure correctness.
|
|
- The `search` crate is a simple command-line that helps run [flamegraph] on top of it.
|
|
- The `helpers` crate is only used to modify the database inplace, sometimes.
|
|
|
|
### Compile and run the HTTP debug server
|
|
|
|
You can specify the number of threads to use to index documents and many other settings too.
|
|
|
|
```bash
|
|
cd http-ui
|
|
cargo run --release -- --db my-database.mdb -vvv --indexing-jobs 8
|
|
```
|
|
|
|
### Index your documents
|
|
|
|
It can index a massive amount of documents in not much time, I already achieved to index:
|
|
- 115m songs (song and artist name) in \~48min and take 81GiB on disk.
|
|
- 12m cities (name, timezone and country ID) in \~4min and take 6GiB on disk.
|
|
|
|
These metrics are done on a MacBook Pro with the M1 processor.
|
|
|
|
You can feed the engine with your CSV (comma-separated, yes) data like this:
|
|
|
|
```bash
|
|
printf "id,name,age\n1,hello,32\n2,kiki,24\n" | http POST 127.0.0.1:9700/documents content-type:text/csv
|
|
```
|
|
|
|
Don't forget to specify the `id` of the documents. Also, note that it supports JSON and JSON
|
|
streaming: you can send them to the engine by using the `content-type:application/json` and
|
|
`content-type:application/x-ndjson` headers respectively.
|
|
|
|
### Querying the engine via the website
|
|
|
|
You can query the engine by going to [the HTML page itself](http://127.0.0.1:9700).

## Contributing
|
|
|
|
You can setup a `git-hook` to stop you from making a commit too fast. It'll stop you if:
|
|
- Any of the workspaces does not build
|
|
- Your code is not well-formatted
|
|
|
|
These two things are also checked in the CI, so ignoring the hook won't help you merge your code.
|
|
But if you need to, you can still add `--no-verify` when creating your commit to ignore the hook.
|
|
|
|
To enable the hook, run the following command from the root of the project:
|
|
```
|
|
cp script/pre-commit .git/hooks/pre-commit
|
|
```
