solr5

问题 Using solr 5.2.0 was wondering is there a query builder API/Jar/Ckient similar to Elasticsearch query builder API or do we have to bassically do String Kungfu to build queries in Solr? 回答1: Unfortunately, in SolrJ there is no such thing as a Builder for the query that goes into the q -Parameter. BUT: As Solr already operates on Lucene, we can as well use the Lucene QueryBuilder. The resulting Query objects (e.g. PhraseQuery) have a toString() method that provides you with the query string you

问题 Just found that Solr 5 doesn't require a schema file to be predefined and it generates the schema, based on the indexing being performed. I would like to know how does this work in the background? And whether it's a good practice or not? Is there any way to disable it? 回答1: The schemaless feature has been in Solr since version 4.3. But it might be more stable only now as a concurrency issue with it was fixed in 4.10. It is also called managed schema. When you configure Solr to use managed

问题 I'm currently working on a project on which I would like to index several data sources (Oracle and HBase) into Solr for full text search. Additionally, I want to be able to visualize the data I index into Solr. I'm still evaluating on whether to use Banana or Hue for this. Here comes the problem: As far as I understood the Solr docs, I can only search on indexed, but non-stored, fields, but not retrieve their original contents. I suppose this will make it quite difficult for the visualizers

问题 The other week I posted a question about removing punctuation from solr search in Drupal. That was using Solr 4. However, since then the development I am doing has changed from solr 4 to solr 5, and now I am having the same problem but the fix at Can't remove punctuation in Solr no longer works. This causes problems when sorting by titles since a lot of content titles have quotes around. <field name="label" type="text" indexed="true" stored="true" termVectors="true" omitNorms="true"/>
