I’ve just noticed that you are also using the index table engine. The index table does not index words below length of 3, so “Le” , “La” are not matched at all, since they are not in the database.
While I do not recommend indexing words below 3 characters, as it may affect the precision of the index table engine, you can change that on the Index table options -> Advnaced panel: https://i.imgur.com/lgx2mbn.png
After lowering and saving the options, you will have to re-create the index table.
