Re: Fuzzy searching documents over multiple fields using Solr

I didn't mention it but I'd like individual fields to contribute to the overall score on a continuum instead of 1 (match) and 0 (no match), which will lead to more fine-grained scoring. A contrived example: all other things equal a tv of 40 inch should score higher than a 38 inch tv when searching

Just want to throw this in: If you're worried about scaling, etc. you could take a look at item-based collaborative filtering instead of user based. i.e: DO NIGHTLY/ BATCH: - calculate the similarity between items based on their properties DO ON EACH REQUEST - have a user store/update it's interes

Re: Sites with Innovative Presentation of Tags and Facets

Something like sliders perhaps? Of course only numerical ranges can be put into sliders. (or a concept that may be logically presented as some sort of ordening, such as "bad, hmm, good, great" Use Solr's Statscomponent to show the min and max values Have a look at tripadvisor.com for good uses/im

Re: Sites with Innovative Presentation of Tags and Facets

Interesting.. say you have a double slider with a discrete range (like tripadvisor et.al.) perhaps it would be a good guideline to use these discrete points for the quantum interval for the sparkline as well? Of course it then becomes the question which discrete values to use for the slider. I te

Re: Sites with Innovative Presentation of Tags and Facets

May I ask how you implemented getting the facet counts for each interval? Do you use a facet-query per interval? And perhaps for inspiration a link to the site you implemented this .. Thanks, Geert-Jan I love the idea of a sparkline at range-sliders. I think if I have time, I > might add them to

Re: Interleaving the results

Indeed, it's just a matter of ordening the results on the client-side IFF I infer correctly from your description that you are guarenteed to get results from enough different customers from SOlr in the first place to do the interleaving that you describe. (In general this is a pretty big IF). So a

Re: Regarding Facet Date query using SolrJ -- Not getting any examples to start with.

Hi Ninad, SolrQuery q = new SolrQuery(); q.setQuery("*:*"); q.setFacet(true); q.set("facet.data", "pub"); q.set("facet.date.start", "2000-01-01T00:00:00Z") ... etc. basically you can completely build your entire query with the 'raw' set (and add) methods. The specific methods are just helpers. S

Re: exclude docs with null field

Additionally, I should have mentioned that you can instead do: fq=field_3:[* TO *], which uses the filtercache. The method presented by Chris will probably outperform the above method but only on the first request, from then on the filtercache takes over. >From a performance standpoint it's probab
