Hi Paul, yes that`s a typical problem in configuring a search engine. A solution depends on your data. Sometimes you can overcome this problem by fine tuning your search engine on boosting level. Thats not easy and always based on trail and error tests.
Another thing you can do is to try to realize a data pre-processing which compensate the reasons of similar content in certain fields, e.g. in a title field. For example if you have products with very similar titles and you boost such a field. The result is, that you always will found all documents in the result list. But if you go on and add some informations (perhaps out of other search fields) in this title field you perhaps can reduce the similarity. (typical example in my branch: Book titles in different volumes, then I add the volumn number and der year to the title field.) Perhaps it is also necessary to cape with a pre-processed deduplication.
