Hi guys, I just noticed (while updating the screen shots for the Solr Search UI documentation [1]) that searching for "blog" doesn't match "Blog.News" from the category of BlogIntroduction any more as indicated in [2].
Debug mode view shows me that "Blog.News" is indexed as "blog.new" which means the text is not split in "blog" and "news" as I would have expected in this case. After checking the Solr schema configuration I understood that this is normal considering that we use the Standard Tokenizer [3] for English text which has this exception: "Periods (dots) that are not followed by whitespace are kept as part of the token, including Internet domain names." Further investigation showed that before 6.0M1 we used the Word Delimiter Filter [4] for English text but I changed this with XWIKI-8911 when upgrading to Solr 4.7.0. I then noticed that the Solr schema has both text_en and text_en_splitting types, the later with this comment: A text field with defaults appropriate for English, plus aggressive word-splitting and autophrase features enabled. This field is just like text_en, except it adds WordDelimiterFilter to enable splitting and matching of words on case-change, alpha numeric boundaries, and non-alphanumeric chars. This means certain compound word cases will work, for example query "wi fi" will match document "WiFi" or "wi-fi". So in case someone wants to use this type instead for English text he needs to change the type in: <dynamicField name="*_en" type="text_en" indexed="true" stored="true" multiValued="true" /> The question is whether we should use this type by default or not. As explained in the comment above, there are downsides.
