Re: [Zope] Ignore stopwords/characters in alphabetical results
Thanks Dieter and others for helping me understand
this problem.
In the end I added the following code to my product:
def norm_title(self):
Returns a normalized copy of the title for
sorting purposes
nt = ''
if hasattr(self, 'title'):
nt = re.sub('^A |^An |^The |\W', ' ',
self.title)
nt = join(split(nt))
return nt
I then added a norm_title index to my ZCatalog for
sorting. I'm a regex newbie so any improvements are
welcome!
Thanks,
Ken

Thus, you only want the change the result order.
Unless you want relevancy ranking (which is not the
case,
depending on your description), ordering has nothing
to
do with the indexes (at least not the text indexes).
Ordering can be done with sequence.sort
(documented in
the Zope Online help system) or with Python's sort
method.
In both cases, you can provide your own comparison
function.
The comparison faction to use the vocabulary to
check for
stopwords (words not known by the vocabulary are
stopwords).

[Zope] Ignore stopwords/characters in alphabetical results
Hi, I have been asked to improve the order of search results, so that stop words and certain characters at the beginning of a title are ignored. Final Report, The Final Report and [Final] Report all need to appear under the letter 'F'. We are running Zope 2.7.8-final with python 2.3.5, under FreeBSD6. Until I was hit with this request, the default ZCatalog and ZCTextIndexes have given good results. I did try to install TextIndexNG3, according to the instructions in the readme but was unable to restart Zope (no message was left in event.log). Would this product make the difference I need?

Re: [Zope] Ignore stopwords/characters in alphabetical results
I have been asked to improve the order of search results, so that stop words and certain characters at the beginning of a title are ignored. Final Report, The Final Report and [Final] Report all need to appear under the letter 'F'. We are running Zope 2.7.8-final with python 2.3.5, under FreeBSD6. Until I was hit with this request, the default ZCatalog and ZCTextIndexes have given good results. ZCTextIndex has a list of stop words that you could probably modify. This should get you pointed in the right direction: http://www.zope.org/Members/dedalu/ZCTextIndex_python hth Jonathan ___ Zope maillist - Zope@zope.org http://mail.zope.org/mailman/listinfo/zope ** No cross posts or HTML encoding! ** (Related lists - http://mail.zope.org/mailman/listinfo/zope-announce http://mail.zope.org/mailman/listinfo/zope-dev )
