In a search query such as: ``` word1 longword2 ``` we typically allow 1 typo on `word1` and 2 typos on `longword2`, as determined by the `minWordSizeForTypos` settings. "Allowing 2...

Stop using serde to serialise values into an LMDB database

1

_(priority: low)_ There are a few places (in both `meilisearch` and `milli`) where we use `serde`'s `Serialize/Deserialize` traits and derive proc macros to write/read values from an LMDB database. I...

An idea to (potentially significantly) reduce the size of the index and speed up indexing tasks: store a less precise proximity between words. Currently, we index all pairs of words...

Indexing documents with a lot of text is too slow

Cancelling an indexing task does not always stop indexing quickly

In Meilisearch v1.1, cancelling an indexing task is not guaranteed to stop the task quickly. There are a few indexing phases which do not listen for the cancellation signal (for...
