[basex-talk] Fulltext processing, "window selection"

Dear BaseX people, it seems to me there is a bug concerning full text processing. The following expression basex "'a single event during the custodial history of a manuscript or other object.' contains text 'custodial history of a manuscript' all words window 5 words" yields "false", shouldn't it yield "true"? Only when I enhance the window width to 10, I get true. 10 would be the required window length if the window started at the beginning of the string. But I think the window should start at the first and end at the last of the words, so 5 should suffice. With kind regards,Hans-Jürgen
