Hi, Is there an example /howto available that I can use to start developing mij own ranking function for full text search? I have looked at the ts_rank source code in src/backend/utils/adt/tsrank.c but that is rather complex an not easy to start learning from. Preferably a minimal boilerplate example with installation instructions in C/C++ ;-). TIA -- Groeten, Joost Kraaijeveld Askesis B.V.
