relevance ranking in ZCTextIndex or equivalent
by Miles Waller 03 Jun '06

03 Jun '06

Hi, I'm planning to implement a text search where (match against the title) ranks more highly than (match in the description) ranks more highly than (matches against the body text). Titles and descriptions are short bits of text, so results in these categories can be ranked just by the frequency that the word appears in that part of the text. Matches against the body text should ideally be ranked more like ZCTextIndex rather than plain frequency. My ideas are: - do three separate searches, and then concatenate the result sets together. problem: making sure there are no duplicates in the list without parsing all the results in their entirety. - hijack the 'scoring' part of the index, so those results with matches in the title can have their scores artificially heightened to achieve the ordering i want problem: it's compleletely opaque without a lot of study whether this would achieve what i want. i'd also need to index the items so the index knew what was in the title, which could be a problem. - index title, description and text separately, and then use dieter's AdvancedQuery product to do the query and combine results problem: is it possible to get at the scores when the documents are returned from the index to be able to order them? are the scores returned separately, or will each query overwrite the last one? Has anyone ever tried to do this - or got any pointers - at all? Thanks in advance, Miles

os module on different os's
by garry saddington 03 Jun '06

I have a Zope application that runs on WinXP and Debian sarge without problems. I am using os.popen and popen2 to run locally installed applications and use their output in Zope (particularly aspell and diction). On Ubuntu Dapper and FC5 however, these os calls fail. Is there a problem with recent Distros and this module? Python version is 2.3 on all systems but I tried 2.4 on FC5 and that failed too. regards garry

The browser might ignore the meta tag inside the document; REQUEST.RESPONSE.setHeader() is safer. Your Expires header does not appear to be correct; try Expires: 0 (anyway it should have the same effect since invalid dates are considered "already expired").

Internet Explorer does not follows redirect, while Firefox does
by Marco Bizzarri 01 Jun '06

01 Jun '06

Hi all. I don't think this is a specific Zope problem. However, I'm experiencing it in a Zope context, and this is why I'm here asking. In a custom Zope application, we have a problem with Internet Explorer. The application follows a "page -> submit -> redirect -> page" cycle. To state more clearly: the page presented to the user can have a link. When the user clicks on the link, something is done, and eventually the user is redirected to the same page which will display different data based on the results of its previous click. The problem is that when IE sees that the result page has the same URL as the first page it does not reload the page and instead shows me the cached version. The problem is not shown with Firefox. As far as I can understand, this is an HTTP header issue, but I would like to know if anyone already has experienced this problem, and has some solution about it.
