Subject Re: MoreLikeThis and dynamicField
Date Sat, 12 Jun 2010 08:37:30 GMT
Hi Lance,

> You cannot give it a wildcard to go find dynamic fields;

ah, ok. But it would be nice to use wildcards.
You correctly guessed that I meant the wildcard querying. The
dynamicField definition is not the problem ... So one can define
<dynamicField name="*_t" type="text" indexed="true" stored="true"/> and
then the query via myfield_t would work.
The termVectors is only for performance reasons, I think (it worked
without this attribute).

Now, regarding "stored" or "not-stored": mlt worked for me if I did:
<field name="myfield" type="text" indexed="true" stored="true"/>

But not if I do
<field name="myfield" type="text" indexed="true" stored="false"/>

Or do I need to configure the field in a different way?

Regards,
Peter.
