For many linguistic investigations, the first step is to find examples. In the 21st century, they should all be found, not invented. Thus linguists need flexible tools for finding even quite rare phenomena. To support linguists well, they need to be fast even where corpora are very large and queries are complex. We present extensions to the CQL ("Corpus Query Language") for intuitive creation of syntactically rich queries, and demonstrate that they can be computed quickly within our tool even on multi-billion word corpora.
