Hello, As I had the same problem I went to the wiki looking for the page to solve my problem again, and there under recent changes I found that you had trashed it.
I can still solve my problem but why don't you keep it for others to benefit from too? As linked it's a recurring problem for several users and the solution is not obvious from the official documentation. http://wiki.apache.org/solr/Troubleshooting%20HTTP%20Status%20404%20-%20missing%20core%20name%20in%20path?action=info -- 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)).
