Marc, we'll probably add option to simple dictionary for 8.5, but I think if you were able to write your own parser it'd be not difficult to write 'simplest' dictionary, which does nothing. Just take simple dictionary and remove lowercasing :) Oleg On Tue, 9 Jun 2009, Marc Mamin wrote:
Hello, I have some columns containig list of codes (e.g. 'Af45De Uz76 I98ht ... ') and I'd like to build full text search indexes on them. As these strings are basically a list of IDs , I don't need any dictionary. I've built an own simplified parser whose output is sufficient. My concern is about the lowercase transformation of the simple dictionary which anyway don't reduce the number of lexemes significantly. I could easily workaround this while rechecking the strings, but I wonder if there is a simple way to disable the lowercse transformation as I don't need it... Maybe someone can also point me to some documentation about writing my own dummy dictionnary? (I'm currently experimenting with 8.3.6, but we will probably implement such functionalities only with 8.4) Thanks, Marc Mamin
