Re: error when post xml data to solr
I get the same error sometimes. I believe it happens when my xml exceeds 4
KB. Is there an upper limit somewhere.
I am using Solr1.3 and using SolrJ to do the post.
Any ideas as to how I can increase the limit?
Thanks!

Faceting Vs using lucene filters ?
Hi, I have a collection of blogs. Each Solr document has one blog with 3 fields - blogger(id), title and blog text. The search is performed over all 3 fields. When doing the search I need to show 2 things: 1. Bloggers block with all the matching bloggers (so if a title, blog or blogger contains the search term, I show the blogger's id) 2. Blogs block that shows the blog titles for the matching blogs. The first block is my problem since it shows multiple instances of the same blogger if that blogger has multiple matching blogs. I can use faceting to show the bloggers but is there a better or more efficient way to do so? I was thinking of creating a lucene filter to do this, is it feasible? Basically, I need the unique bloggers from the index whose blogs match a given search term.

RE: Faceting question
Thanks Peter. That will be my work-around, but I was hoping to find a more elegant solution ;) I am not that knowledgeable about the solr architecture but if there is a way it can be done in a more elegant way I might be willing to put the extra time to code it..

Re: Alphabetical Facets
Will there be a way to do reverse alphabetical ordering in addition to alphabetical? a->z and z->a ?

Re: Getting only size of getFacetCounts , to simulate count(group by( a field) ) using facets
Hi, Not sure what the resolution on this has been. But, I also have this need and I am using 1.2 release of solr. If there is a workaround so I can get this functionality, please advise. It will be very helpful. Thanks.

Unique field and EmbeddedSolr issue..
Hi, I have 2 questions: 1. I am using EmbeddedSolr and using example from here: http://wiki.apache.org/solr/EmbeddedSolr I just noticed that there is a note there saying that the page is out of date, is that true and if yes is there an example that uses Solrj? 2. I am using EmbeddedSolr and I see that my documents are getting added multiple times even if I have specified the uniqueKey field. I am using Solr 1.2 and following are the relevant entries from my schema.xml: id Please let me know what I could be doing wrong. I realize this is holiday time though we are very close to our release date and would really appreciate any kind of immediate help.

Stop words and exact phrase
Hi all, Is there a config setting that I could use to not remove stop words when doing an exact phrase match. For example when searching for "the world" (in quotes) I would like to look for just that and not get results for just "world". When I look at the analysis, I see that word "the" is removed by the StopFilter even if it is in quotes. So is there a work-around to solve this?

Re: Stop words and exact phrase
Hi wunder, Thanks for your response. I am still a little confused. Solr's analysis page shows that the stop word is removed from the query - its got nothing to do with the indexing imo. If indexing has removed the stop words then I should not get any results right? But I get the results with the stop word removed. How do I tell Solr to send phrase queries to a field other than default? Will I have to code that or is it just a config setting? Thanks.
