We have just released the new Lexique search engine — and the performance boost is quite remarkable.
The previous system needed nearly 15 seconds to start; the new one launches almost instantly.

What’s new:

• Tag-based navigation
Databases are now organized using tags (“AoA” for Age of Acquisition, “Reaction times”, etc.). This makes it easy to immediately identify all databases containing a given type of information.

• Language selection
You can now directly choose the language. For example, the English section provides access to several classic and widely used databases in the anglophone research community.

• A detailed information panel
The “?” opens a full information sheet for each database: description, website, number of words, references, and other useful metadata.

• Multi-database querying
The ability to query multiple databases at once remains intact, now with a much more responsive interface.

The engine is available here:
