Dear Jerome, from personal experience full-text searching in PostgreSQL can be quite powerful but it's not simple, it requires thought, planning and coding. PostgreSQL mainly provides an efficient token matching mechanism supporting positional information and weights, but natural language processing and normalization is pretty basic.
If you don't mind writing a couple of user-defined functions to take control of lexeme normalization, then tsvector/tsquery support can be a very powerful tool for custom search engines. regards, Michael 2009/11/12 Jérôme Etévé <jerome.et...@gmail.com> > Hi all, > > I'd like to implement a full text search with postgresql, and I can't find > a text search configuration that would just: > > map unicode accentuated letters to an un-accentuated equivalent > tokenize the words (and skip any non word characters) > no stopwords > lower case the tokens > > How can I achieve this?
