# meili-core
|
|
|
|
A search engine based on the [blog posts serie](https://blog.algolia.com/inside-the-algolia-engine-part-1-indexing-vs-search/) of the great Algolia company.
|
|
|
|
If you want to be involved in the project you can [read the deep dive](deep-dive.md).
|
|
|
|
This is a library, this means that binary are not part of this repository
|
|
but since I'm still nice I have made some examples for you in the `examples/` folder.
|
|
|
|
|

|
## Performances
|
|
|
|
We made some tests on remote machines and found that we can handle, on a server that cost 5$/month with 1vCPU and 1GB of ram and on the same index and with a simple query:
|
|
|
|
- near 190 users with an average response time of 90ms
|
|
- 150 users with an average response time of 70ms
|
|
- 100 users with an average response time of 45ms
|
|
|
|
Network is mesured, servers are located in amsterdam and tests are made between two different datacenters.
|
|
|
|
|
|
|
|
## Usage and examples
|
|
|
|
Meili-core work with an index like most of the search engines.
|
|
So to test the library you can create one by indexing a simple csv file.
|
|
|
|
```bash
|
|
cargo build --release --example csv-indexer
|
|
time ./target/release/examples/csv-indexer --stop-words misc/en.stopwords.txt misc/kaggle.csv
|
|
```
|
|
|
|
The `en.stopwords.txt` file here is a simple file that contains one stop word by line (e.g. or, and).
|
|
|
|
Once the command finished indexing you will have 3 files that compose the index:
|
|
- The `xxx.map` represent the fst map.
|
|
- The `xxx.idx` represent the doc indexes matching the words in the map.
|
|
- The `xxx.sst` is a file that contains all the fields and the values asociated with it, it is passed to the internal RocksDB.
|
|
|
|
Now you can easily run the `serve-console` or `serve-http` examples with the name of the dump. (e.g. relaxed-colden).
|
|
|
|
```bash
|
|
cargo build --release --example serve-console
|
|
./target/release/examples/serve-console relaxed-colden
|
|
```
|
