RE: [Zope-dev] more on keyword indexes
OK. that clears a lot up. Im guessing that you can query all indexes that intersect with your query set( UNION ) by using the syntax Steve mentioned. ( or something like that ). as for the "unpredictable results", I found that querying the index produces different results every time I queried it. The steps to reproduce this are tedious and numerous. thanks, josh Josh Zeidner writes: > > However, Dieter says that it is not yet possible to > query for more than one keyword at once. At least, it was not my intention to say such a thing. You can search for several keywords at once, but the result is the *UNION* of the results for the single keywords. I.e., the keywords are combined with an "OR". You can not search for the objects with all the keywords you specify. I.e. you do not get the effect of ANDing your keywords.

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 . 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.

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 or 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.

One useful use is to limit a query on a SiteIndex type of catalog to just a sub-tree of your site.
