The solution would be a way to tell Solr/lucene which documents/indices to query, i.e. query only the union/intersection of the documents in which k1,...kn appear, instead of query all indexed documents and apply the ranking function (which will give weight to documents that contains k1...kn). > -- > View this message in context: > http://lucene.472066.n3.nabble.com/How-do-I-make-sure-the-resulting-documents-contain-the-query-terms-tp3031637p3033451.html > Sent from the Solr - User mailing list archive at Nabble.com. > -- Regards, K. Gabriele --- unchanged since 20/9/10 --- P.S. If the subject contains "[LON]" or the addressee acknowledges the receipt within 48 hours then I don't resend the email. subject(this) ∈ L(LON*) ∨ ∃x. (x ∈ MyInbox ∧ Acknowledges(x, this) ∧ time(x) < Now + 48h) ⇒ ¬resend(I, this). If an email is sent by a sender that is not a trusted contact or the email does not contain a valid code then the email is not received. A valid code starts with a hyphen and ends with "X". ∀x. x ∈ MyInbox ⇒ from(x) ∈ MySafeSenderList ∨ (∃y. y ∈ subject(x) ∧ y ∈ L(-[a-z]+[0-9]X)).
