Although several syntactically annotated corpora (or treebanks) exist for Dutch, they are seldomly used for descriptive linguistic research because there are no easy-to-use exploitation tools available.This demonstration paper describes GrETEL, a linguistic search engine (http:// nederbooms.ccl.kuleuven.be/eng/gretel)that enables non-technical users to consult treebanks in a user-friendly way.Instead of a formal search expression, a natural language example is used as input to the system, allowing users to search for similar constructions as the example they provide.In the first version of GrETEL, only written Dutch (LASSY) was included.Based on user requests we have now included the Spoken Dutch Corpus (CGN) as well.
