a concurrent indexer combined with fast and relevant search algorithms

Introduction

This engine is a prototype, do not use it in production. This is one of the most advanced search engine I have worked on. It currently only supports the proximity criterion.

Compile and Run the server

You can specify the number of threads to use to index documents and many other settings too.

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 ~1h and take 107GB on disk.
• 12m cities (name, timezone and country ID) in 15min and take 10GB on disk.

All of that on a 39$/month machine with 4cores.

You can feed the engine with your CSV (comma-seperated, yes) data like this:

printf "name,age\nhello,32\nkiki,24\n" | http POST 127.0.0.1:9700/documents content-type:text/csv

Here ids will be automatically generated as UUID v4 if they doesn't exist in some or every documents.

Note that it also support 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.

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
