Re: [Zope-dev] more on keyword indexes
Hello, Thanks for all the replies. Its seems there are two conflicting answers to my questions. Steve Alexander says that it is possible to query indexes using the syntax dtml-in "Catalog.searchResults( doc_keywords = ['one','two','ect'] . However, Dieter says that it is not yet possible to query for more than one keyword at once. It seems to me that these two sentiments are mutually exclusive. Am I mistaken here? -josh Josh Zeidner writes: OK. Is it possible to query keyword indexes for several keywords at once? Not that I know of. You either have to extend ZCatalog or wait some time.

I've now taken this over, and while I don't have the bandwidth to track zope-dev constantly, I do try to find things. I've also fixed untold numbers of bugs that were easy to do (there are some that are structural and will have to wait), and 2.3 will have a *substantially* better Catalog.

Re: [Zope-dev] more on keyword indexes
Hi Josh, I use KeywordIndexes a lot. Just for kicks, I implemented what you describe below in Zope2.3 grabbed fresh from CVS just now. I used DTML Documents for the objects to catalog, and I added a lines property called KW to each one. I queried the catalog using syntax like dtml-in "Catalog(KW=['one', 'two'])" or dtml-in "Catalog(KW='purple')" Josh Zeidner wrote: Hello, I did a little more investigiation into the problem, and couldnt really find any documentation anywhere on what the actual semantics are of keywords and how they are queried. For instance: I have three classes and each has an keyword index named KW: ObjectOne:KW = ['one','blue','furry'] ObjectTwo:KW = ['two','flying','purple'] ObjectThree: KW = ['three','one-eyed','purple'] If I were to query the ZCatalog with the following set of words: ['purple'] I would expect to get: ObjectTwo ObjectThree Yes, that's what you get. Right? If I query the database with ['one','two'] ( if this type of thing is at all possible ), I get : ObjectOne ObjectTwo Yes, that's what you get. This seems like the obvious result: BUT: it depends if you want a AND/OR type search. It is an OR search. I could also expect to get nothing( if its an AND type search because no records match 'one' and 'two' ). Here is better example, what if I queried: ['purple','one-eyed']. Would I be expecting only ObjectThree or [ ObjectThree, ObjectTwo ] ( because they both match the keyword purple( a logical set-intersection ) ). You get ObjectTwo and ObjectThree. Also I found the keyword indexes to have some more obvious bugs. If I only used one keyword for the matching critiria, for instance if I used 'purple' , I would only get ObjectTwo. I get ObjectTwo and ObjectThree, as I'd expect. Is anyone else using keyword indexes? In what way are you using them? All sorts of things. One useful use is to limit a query on a SiteIndex type of catalog to just a sub-tree of your site.
