Subject RE: Filtering query results
Date Fri, 20 Nov 2009 16:04:07 GMT
Hi Aseem -

I had a similar challenge.  The solution that works for my case was to
add "role" as a repeating string value in the solr schema.  

Each piece of content contains 1 or more roles and these values are
supplied to solr for indexing.

Users also have one or more roles (which correspond exactly to the
metadata placed on content and supplied to Solr.)

So when peforming the search query, we add add an fq parameter to filter
search results.  For example q=Search Phrase&fq=role:(role1 || role2 ||
role3) 

Note that ultimate restriction to content is handled elsewhere, this is
only done as a filtering mechanism for search results.  Additionally, we
do not have unlimited sets of roles and that helps to keep the query
string on the HTTP GET to a minimum.  Finally, the roles for my system
are additive such that if there is a match on any one role - the user
has access - so an OR clause works.  Your system may have more complex
role rules.

Subject: Filtering query results

Hey Guys,
I need to filter out some results based on who is performing the search.
In other words, if a document is not accessible to a user performing
search, I don't want it to be in the result set. What is the
best/easiest way to do this reliable/securely in Solr?
Thanks
