Ok, try organising your kb in a way where it is structured for individual topics if you havent already. Make sure to name the kb the correct topic and give the kb a description. for example: create a kb for only a2 licence motorbikes, name it A2 Licence motorbikes and give it that specific description. the way the kb works is first it will search the titles of the kbs, then the descriptions and then the information within the kb
