Question regarding wildcards and dismax

[Roland Villemoes <rv...@alpha-solutions.dk>]

Hi all,

We have a web application build on top of Solr, and we are using a lot of facets - everything works just fine.
When the user first hits the searchpage - we would like to do a "get all query" to the a result, and thereby get all facets so we can build up the user interface from this result/facets.

So I would like to do a q=*:* on the search. But since I have switched to the dismax requesthandler this does not work anymore. ?

My request/url looks like this:


a)       /solr/da/mysearcher/?q=*:*           Does not work

b)      /solr/da/select?q=*:*                          Does work


But I really need to use a) since I control boosting/ranking in the definition.
Furthermore when the user "drill down" the search result, by selecting from the facets, I still need to get the full searchresult, like:

/solr/da/mysearcher/?q=*:*&fq=color:red     Does not work.

Can anyone help here? I think that the situation for my web application here is quite normal (Get a full resultset to build facets, then let the user du a drill down etc....)


Thanks a lot in advance

Have a look at the q.alt parameter 
(http://wiki.apache.org/solr/DisMaxRequestHandler#q.alt) which is used 
for exactly this issue. Basically putting q.alt=*:* in your query means 
you can leave out the q parameter if you want all documents to be selected.
