Re: [Zope] searching with foreign characters in the ZCatalog

In my opinion, this is correct - Jurgen is spelled incorrectly. There are two ways to handle this: * either by normalization: you transform your words into a normal form and index this. You make the same normalization for search terms. This way, any two search terms with the same normalization are equivalent. In your case, your normalization could replace ü by u. * by an expansion of your search terms to search as well for similar words. This technique is often used to search for words that sound similarly but can be used for other purposes as well. Applied to your case: when someone searches for Jurgen you would effectively replace it with Jurgen or Jürgen. -- Dieter ___ 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 )

In my opinion, this is correct - Jurgen is spelled incorrectly. However, I am having some clients push hard to have it behave differently. From what I've looked at, I haven't seen a way to make FieldIndex ignore or somehow manipulate special characters, nor have I seen any products that provide a new index type to specifically deal with this. Does anyone know if there is something out there to help with this? Look at TextIndexNG3 and its normalization support. -aj pgpyY1inWuI6P.pgp Description: PGP signature ___ 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 )
