How to get default result?

[richardr <ri...@yahoo.de>]

Dear list,

i got a question regarding my address search:
I am searching for address data. If there is one address field not definied
(in this case the housenumber) for the specific query (e.g. city = a, street
= b, housenumber=14), I am getting no result. For every street there exists
at least one housenumber (=0).

Is it possible to get this default value (housenumber 0) as a result, if the
user is searching for the housenumber 14, which does not exist in our model?

Thanks in advance,
Richard

Tomás, thanks for answer. It was very helpful!
We are using your first option now with a workaround. :)

But initially we thought not to modify the user's request. So if the user
requests the housenumber=14, we do not want to parse the request and add an
"OR 0". If there is no housenumber=14 solr should response with the defined
default value.
Does someone know if there is a way to do this?

Thanks,
Richard

Hi Richard, are you setting the value to 0 at index time when the
housenumber is not present? If you are, this would be as simple as modify
the query at the application layer to city = a, street= b, housenumber=(14
OR 0).
If you are not doing anything at index time with the not present
housenumbers, you could do something like city:a AND street:b AND
(housenumber:14 OR NOT housenumber:[* TO *]).

First option is better if you ask me. You can set the default value on your
schema. See http://wiki.apache.org/solr/SchemaXml#Fields
