Hello,
My previous e-mail with a CJK example has received no replies. I verified
that this problem also occurs for English. For example in the case of the
word "fire-fly" , The ICUTokenizer and the WordDelimeterFilter both split
this into two tokens "fire" and "fly".
With an edismax query and a must match of 2 : q={!edsmax mm=2} if the
words are entered separately at [fire fly], the edismax parser honors the
mm parameter and does the equivalent of a Boolean AND query. However if
the words are entered as a hypenated word [fire-fly], the tokenizer splits
these into two tokens "fire" and "fly" and the edismax parser does the
equivalent of a Boolean OR query.
I'm not sure I understand the output of the debugQuery, but judging by the
number of hits returned it appears that edismax is not honoring the mm
parameter. Am I missing something, or is this a bug?
I'd like to file a JIRA issue, but want to find out if I am missing
something here.
Details of several queries are appended below.
