Hi all,
With the goal of allowing the use of wildcards anywhere in a ZCTextIndex query, and also ignore accentuated characters, I am developping a custom Lexicon, Splitter and CaseNormalizer. These are packed into a Product
Why don't you look at TextIndexNG3 where almost everything is pluggable and configurable? -aj
Hi,
Why don't you look at TextIndexNG3 where almost everything is pluggable and configurable?
Firstly because I wasn't aware of its existence... Secondly (now I've seen it) because it seems particularly heavy for my use: It proposes many features, of which I shall only need 2 I have a very tight deadline on this and I'm new to Zope, python and the likes... I can't see how easy it's going to be to use: how long will it take me to transition from ZCTextindexes to TextIndexNG3's? (I've already spent quite some time integrating the ZCTextIndex queries into my code) If these issues are unfounded, I would be happy to use TextIndexNG3, but so far I think I'm better off fixing the couple of bugs in my Lexicon (apart from these, it's finished) TIA for your input on this :) Jonathan -----Message d'origine----- De : Andreas Jung [mailto:lists@zopyx.com] Envoyé : mercredi 2 mai 2007 10:57 À : Winterflood, Jonathan; zope@zope.org Objet : Re: [Zope] custom Lexicon developpement problems --On 2.

These are packed into a Product The more permissive globbing rules work fine, and the accent-bashing ToAsciiCaseNormalizer too (this looks like a good alternative to indexing a method that would remove the accents from the field we're interested in <suggested on a CPS list>) Hovever, I'm having problems creating indexes that use them: I created the lexicon and indexes via the catalog.xml file, but the 'indexed_attr' fields are ignored (therefore, creating indexes on multiple fields isn't possible). In the ZMI, in portal_catalog, I cannot select the lexicon for use when I add a ZCTextIndex Does anyone know how to go about these problems? </snip> Dieter's Manageable Indexes product may be of some use: http://www.dieter.handshake.de/pyprojects/zope/#ManagableIndex Jonathan
You may want to look at http://www.zope.org/Members/shh/ UnicodeLexicon for inspiration. Stefan On 2. Mai 2007, at 10:50, Winterflood, Jonathan wrote:

Hi, Indeed, I had a good look at your UnicodeLexicon while writing mine. The problem is I don't really understand how some of the things work. My main issue is how to integrate the 'indexed_attr' field, but I can't see what is necessary to activate this functionality Could you maybe explain this?

What's why I pointed you to TextIndexNG3 where every component has a well defined interface and is pluggable and replaceable through ZCML. -aj

Since LOCK is a SQL statement you can *of course* integrate with ZSQL method which basically send the configured SQL statements straight down to the database server...where is the problem`? -aj
