Well, back then, moin mapped blank to underscore. Initially we thought that copying this idea from mediawiki was a good idea, but soon later we found it was not. > We converted to 1.9.2 and now they are complaining about searches not > finding pages.

That's likely because the tokenizer splits on blanks and on CamelCase lower-upper transitions, but not on underscores. > I guess I could have changed underscores to spaces during the > conversion, but it is too late now.

I did a quick test and it didn't find a single word if the title was made of words connected with underscores. > I looked in the 1.9.3 change list and can find no explanation for the > difference between search or indexing in 1.9.2 and 1.9.3.

I don't think it is a configuration issue. I am currently trying to extend the tests with the underscore issue and fix the code, so the tests don't fail. ------------------------------------------------------------------------------ Download new Adobe(R) Flash(R) Builder(TM) 4 The new Adobe(R) Flex(R) 4 and Flash(R) Builder(TM) 4 (formerly Flex(R) Builder(TM)) enable the development of rich applications that run across multiple browsers and platforms.
