[Xapian-discuss] Processing the Xapian results

[Arjen van der Meijden]

Afaik you pre-process your form-input data using php?

In that case you can construct a list of all forums a user is allowed to 
see. That list can be easily combined with the forums the user wants to 
include in the search.

On the indexing-site you can add a boolean-term indicating the topic's 
forumid.

And in the search-code you can than add a boolean-OR-construction for 
that list of forums a user may see. (in SQL-terms you'd add something 
like: AND topic.forumId IN (f1, f2, f3) which you'll have to expand to:
AND (topic.forumId = f1 OR topic.forumId = f2 OR topic.forumId = f3)).

Best regards,

Arjen
