Ranking Question.

Hi, Maybe a trivial/stupid questions but: I have a fairly simple schema with a title, tags and description. I have my own ranking/scoring system that takes into account the similarity of each tag to a term in the query but now that i want to include also the title and description (the description

Re: [2] SQL Update

I could create a list of field name + type, but doing so I might as well create it and add it to fields in schema.xml. Does solr reread the schema file when I post an add action or only on starup (or someother point)? In general, I wonder if adding the suffix for dynamic fields is not posing

Re: HA and load balancing Qauestion

Thanks for the reply Yonik. I'm not using HTTP and using a wrapper to wrap Solr for searching. I'm using RPC to talk to multiple servers. Can I point 2 Solr instances to the same index partition, having the same path in SolrConfig? Is this safe or I need to make 2 copies of the same index

Re: HA and load balancing Qauestion

Thanks Yonik and Chris for your confirmation. Chris, these are read-only index partitions. I perform updates/deletions on a master index which will be snapshotted at some fixed intervals. I'll look into the Collection Distribution of Solr. Sounds very powerful. I'm struck with Solr requiring an

Re: HA and load balancing Qauestion

Thanks Hoss for the clarification. I think I can make a copy of the index for searching and rename 'em. I think I can work around this one but good to know the bigger picture. Venkatesh On 3/8/07, Chris Hostetter [EMAIL PROTECTED] wrote: : I'm struck with Solr requiring an index directory

stack trace response

Hello, We have a front application server that uses Solr to search our contents. If the front application calls Solr with /select but missing q parameter, Solr returns a stack trace with its response body, while we expect XML response with an error message ( the stack trace in the XML). Is it a

Re: stack trace response

I agree, the display is a bit weird. But, if you check the response headers it the response code is 400 Bad Request In firefox or IE, you would need to inspect the headers to see what is going on. The issue is that /select uses a servlet that writes out a stack trace for every error it hits
