Apache Solr Reference Guide 5.0
Greetings, I was looking at the PDF version of the Apache Solr Reference Guide 5.0 and noticed that it has no TOC nor any section numbering. http://apache.claz.org/lucene/solr/ref-guide/apache-solr-ref-guide-5.0.pdf The lack of a TOC and section headings makes navigation difficult. I have just started making suggestions on the documentation and was wondering if there is a reason why the TOC and section headings are missing? (that isn't apparent from the document) Thanks! Hope everyone is near a great weekend! Patrick
Re: Apache Solr Reference Guide 5.0
Shawn, Thanks! I was using Document Viewer and not Adobe Acrobat so was unclear. The TOC I meant was as in a traditional print publication with section #s, etc. Not a navigation TOC sans numbering as in Adobe. The Confluence documentation (I can't see the actual stylesheet in use, I don't think) here: https://confluence.atlassian.com/display/DOC/Customising+Exports+to+PDF Says: * Disabling the Table of Contents To prevent the table of contents from being generated in your PDF document, add the div.toc-macro rule to the PDF Stylesheet and set its display property to none: * Which is why I was asking if there was a reason for the TOC and section numbering not appearing. They can be defeated but that doesn't appear to be the default setting. This came up because a section said it would cover topics N - S and I could not determine if all those topics fell in that section or not. Thanks! Hope you are having a great day!

(that isn't apparent from the document) The TOC is built into the PDF and it's up to the PDF viewer to display it. Here's a screenshot of the ref guide in Adobe Reader with a clickable TOC open. https://www.dropbox.com/s/3ajuri1emj61imu/refguide-5.0-TOC.png?dl=0 Section numbering might be a good idea, if it's not too intrusive or difficult. Thanks, Shawn
Solr-3.5.0/Nutch-1.4 - SolrDeleteDuplicates fails
Greetings! On the Nutch Tutorial: I can run the following commands with Solr-3.5.0/Nutch-1.4: bin/nutch crawl urls -dir crawl -depth 3 -topN 5 then: bin/nutch solrindex http://127.0.0.1:8983/solr/ crawl/crawldb -linkdb crawl/linkdb crawl/segments/* successfully. But, if I run: bin/nutch crawl urls -solr http://localhost:8983/solr/ -depth 3 -topN 5 It fails with the following messages: SolrIndexer: starting at 2011-12-11 14:01:27 Adding 11 documents SolrIndexer: finished at 2011-12-11 14:01:28, elapsed: 00:00:01 SolrDeleteDuplicates: starting at 2011-12-11 14:01:28 SolrDeleteDuplicates: Solr url: http://localhost:8983/solr/ Exception in thread main java.io.IOException: Job failed! at org.apache.hadoop.mapred.JobClient.runJob(JobClient.java:1252) at org.apache.nutch.indexer.solr.SolrDeleteDuplicates.dedup(SolrDeleteDuplicates.java:373) at org.apache.nutch.indexer.solr.SolrDeleteDuplicates.dedup(SolrDeleteDuplicates.java:353) at org.apache.nutch.crawl.Crawl.run(Crawl.java:153) at org.apache.hadoop.util.ToolRunner.run(ToolRunner.java:65) at org.apache.nutch.crawl.Crawl.main(Crawl.java:55) I am running on Ubuntu 10.10 with 12 GB of memory, Java version 1.6.0_26. I can delete the crawl directory and replicate this error consistently. Suggestions? Other than ...use the way that doesn't fail. ;-) I am concerned that a different invocation of Solr failing consistently represents something that may cause trouble elsewhere when least expected. (And hard to isolate as the problem.) Thanks! Hope everyone is having a great weekend!
