dismax + wildcard

[Jan Kammer <ja...@mni.fh-giessen.de>]

Hi there,

what is the best way to search all fields AND use wildcards?
Somewhere I read that there are problems with this combination... 
(dismax + wildcard)


Thanks,


Jan

There are some open issues (not for 1.4 at this point) to make dismax
more flexible or add wildcard handling, e.g:

https://issues.apache.org/jira/browse/SOLR-756
https://issues.apache.org/jira/browse/SOLR-758

You might participate in those to try to get this in a future version
and/or get a working patch for 1.4

It's a feature of dismax. WildcardQuery cannot be used in dismax q 
parameter.

You can copy the "all fields" to a destination field by using
copyField, then search the destination field with wildcards
(without using dismax).

Thread Hijacking on Mailing Lists

When starting a new discussion on a mailing list, please do not reply to
an existing message, instead start a fresh email.  Even if you change the
subject line of your email, other mail headers still track which thread
you replied to and your question is "hidden" in that thread and gets less
attention.   It makes following discussions in the mailing list archives
particularly difficult.

 Hi Jan,
 You could write a dismax request handler and then then in the query you could specify like -

q=something&qt=dismaxhandler&fq=type:something

This might help.

Thanks
