----------------------------------------
Hi Joe,
I'm unable to reproduce on Postgres with trunk and release. Did you use a
specific weight for gismotron ?
> Duplicates in Search Results
> ----------------------------
>
> Key: OFBIZ-1514
> URL: https://issues.apache.org/jira/browse/OFBIZ-1514
> Project: OFBiz
> Issue Type: Bug
> Components: product
> Affects Versions: SVN trunk
> Reporter: Joe Eckard
> Priority: Minor
> Attachments: patch.txt
>
>
> If a product has multiple keywords with identical roots and different
> relevancy weights and the product is within a set of search results that span
> multiple pages, then it will be duplicated in the results display. This is
> because ProductSearch is doing a "distinct" on productId, relevancyWeight(s)
> instead of grouping by the productId. (And the attempt at duplicate removal
> only happens on a page-by-page basis.)
> I'm attaching a small proof-of-concept patch to make grouping by productId
> the default - it appears to work well with various combinations of search
> criteria (multiple keywords, features, feature cats, categories, etc.) but I
> haven't done a tremendous amount of testing. (Only using PostgreSQL and Derby)
> From the comments in the ProductSearch code it looks like it was done this
> way once, but it may have caused problems with Oracle. Does anyone know what
> that problem was, or can anyone check this patch against oracle?
