Strange query behaviour using splitOnCaseChange=1

Hi all,

 

I had indexed a text with the word "InterContinental" with fieldType
text (with the default filters just removing the
solr.SnowballPorterFilterFactory).

 

As far as I understand, using the filter solr.WordDelimiterFilterFactory
with splitOnCaseChange="1", this word is indexed as:

 

term text

inter

continental

intercontinental

 

When I search for "continental" the article is returned. 

When searching for "intercontinental" the article is returned

When searching for "Inter Continental" the article is returned

When searching for "Inter AND Continental" the article is returned

When searching for "InterContinental" the article is NOT returned

 

Can anyone explains why the last search didn't return the article?

 

Thank you,

Frederico,

Doesn't preserveOriginal="1" help you?
