Hi everybody,
I have a prototype Solr schema defining a couple of dynamic fields
pattern. With my usage of Solr, new dynamic fields can be added at any time.
What I want to do is to be able to search over all fields of my schema
(dynamic and not). Since the application layer doesn't know what fields
exists (without querying it), I don't want to list all of them in the
search query, and I don't want to list all of them in the dismax query
handler.
However, the field "*" is not existing (wildcards are not supported as
fields), so I can't send queries such as "q=*:testString".
So, apparently that one of the only way to do this considering my
usecase above, is to create a field "all_text", and then to setup the
appropriate copyFields so that each time a new dynamic field is created,
then that its value get indexed in that "all_text" field. The I made
this field the default search field.
This solution works, even if I don't like seeing all this content
duplicated.
However, I don't want to get the content of that field in any resultset
of any search query. I want it to be searchable, but I don't want it
added in the resultset.
I can't use the FL parameter because I don't want to list all of them in
the query to Solr, and apparently that we can't use FL to "ignore" a
list of fields.
So, I took at look at the definition of my "all_text" field, and I found
this table:
http://wiki.apache.org/solr/FieldOptionsByUseCase
It suggests that if this field is "indexed=true" and "stored=false",
that it would be searchable without being added to the resultset.
However, this doesn't work.
When I test it, if I test it with "stored=true", it works as expected,
if I test with with "stored=false" the resultset is empty.
So, given my needs, given my usecases and given these tests, does
anybody know why "stored=false" doesn't work th way I thought it was
working, or if there would be a way to ignore a field in a search
resultset, or if there is another way to search over all dynamic fields
without using this copyField "trick".
Finally I can't change the codebase, I have to use what is shipped by
default by the Solr project.
Thanks for your help!
Take care,
Fred
