Querying multiple dynamicField

[Renaud Delbru <re...@deri.org>]

Hi,

We would like to know if there is an efficient way to query multiple 
dynamicField at the same time, using wildcard in the field name. For 
example, we have a list of dynamic fields "sentence_*" and we would like 
to execute a query on all the "sentence_*" fields.
Is there a way to execute such queries on Solr 1.3 / Lucene 2.3 ?

Regards.

The idea was to keep separated a certain number of lines (or sentences) 
in a document without using the GapPosition trick between field 
instances. I found that the use of multiple dynamic fields is a cleaner 
and generic approach.
By using the copyField, I duplicate data inside the index but I loose 
also the line distinction.

I think the addition of wildcards in the field name can be a good 
addition to the Solr features. This will give us the ability to query 
only a certain "type" of dynamic field (typeA_*, typeB_*, etc.).

Regards.

You can use the <copyField> directive to copy all 'sentence_*' fields into
one indexed field. You then have a named field that you can search against.

sorry, nothing currently will do that.

There is discussion about how to do it, but nothing concrete
