Hello, We have an interesting and we guess common machine learning problem. Polyvore (the company I work for) has a few million products in its index. For each product we have the following information: - keywords extracted from title, description, tags - other meta information like colors, bran

Re: Disable coord

Thanks for your reply. Nested boolean queries is a valid concern. I also realized that isCoordDisabled needs to be considered in BooleanQuery.hashCode so that a query with coord=false will have a different cache key in Solr. On Thu, Nov 12, 2009 at 12:12 PM, Chris Hostetter wrote: > > : I want

BoostedQuery Performance

Hi, I'm trying the BoostQParserPlugin and FunctionQuery to enable query time boosting. It works better than bf (boost function) because it multiplies the relevancy score by the boosts. However I noticed significant performance issues with it. The more functions I use as boosts, the slower it ge

Slow performance using MatchAllDocsQuery with filter query

Hi, I've noticed some bad performance in faceted browsing, when the query is empty (so the MatchAllDocsQuery is used) and there are only filter queries. An example of the search url is: http://hostname:8080/solr/select/?q=&qt=dismax&fq=color:%2300 One idea is to switch to the StandardRequest

Timeout in remote streaming

Hi, I'm sending a local csv file to Solr via remote streaming, and constantly get the "500 read timeout" message. The csv file is about 200MB in size, and Solr is running on Tomcat 5.5. What types of timeout related Tomcat params I can adjust to fix this? Thanks in advance. - Guangwei

Handling empty query

Hi, Does Solr support empty queries? It'll be nice if Solr can return all results if q is null. Otherwise, I guess I'll have to write a customized request handler. Any thoughts? Thanks in advance. - Guangwei

Re: Color search

Thanks for all the replies. I think creating 10 fields and feeding each field with a color's value for 10% from that color is a reasonable approach, and easy to implement too. One problem though, is that not all products have a total of 100% colors (due to various reasons including our color extrac

Color search

Hi, We're running an e-commerce site that provides product search. We've been able to extract colors from product images, and we think it'd be cool and useful to search products by color. A product image can have up to 5 colors (from a color space of about 100 colors), so we can implement it easil
