问题 I have one file named item.csv, which contains around 100 products for now and it is indexed using SOLR.My requirements is if I add more data around 10 to 100 products on daily basis, do I need to re-index the whole document daily,or does SOLR support indexing only those new data? Can anyone please clarify my question. Thanks in advance. 回答1: Yes, you can just add new documents to the index without having to rebuild the whole index. If you mean appending data to (or updating) an existing

问题 I am writing a custom filter in Solr to post a token to Apache Stanbol for enhancement and index the response to a different field in the same document. In my test code below I have got the Stanbol response and have added it as a new document to Solr. My requirement is to add the stanbolResponse as a field value to the same document being indexed. I think this can be done if I can retrieve the document Id from the TokenStream in the filter. Can anyone please help me with a sample code/example

问题 I started to learn Solr and I am trying to write a WordCount-example with Solr and Spark. But I have problem, perhaps with the imports or with the dependencies. You can look at my code below.. My dependencies: <groupId>com.lucidworks.spark</groupId> <artifactId>spark-solr</artifactId> <version>2.1.0</version> <groupId>org.apache.solr</groupId> <artifactId>solr-solrj</artifactId> <version>7.6.0</version> My Code: object Solr extends SparkApp.RDDProcessor { def getName: String = "query-solr

问题 We are running a TomCat servlet (Railo) for a public facing REST application. I've started implementing SolrJ to control a standalone Solr cluster. Queries are working well, but I'm scratching my head over the flow vs. just using the straight HTTP interface Solr provides. I thought there was some performance benefit to using SolrJ which is why I started implementing it, but from what I'm reading and seeing in response times, I think I was wrong on that account (?). Is there any real advantage

问题 In my entity clas, I defined id: @Field("id") protected Long id; then in solr4.0.0 schema.xml, i define: <field name="id" type="long" indexed="true" stored="true" /> <uniqueKey>id</uniqueKey> then solr throws exception on startup. If 'id' is defined as 'string' type, no exception. so my question is: what's the solution if i insisted on defining 'id' as long type. 回答1: Check SOLR-2997 It seems QueryElevationComponent needs the Unique key in String format. So if you don't need it you can remove

问题 I'm working on an Solr integration for an e-commerce site. I want to offer a jQuery Slide Range UI (refer http://jqueryui.com/slider/#range). So visitor will be offered with a slider with min and max price on the page which they can use to define a range and accordingly the filter is applied. On Solr side, I understand how to make a range filter query on this. However, for displaying a range I need min and max price value. I'm not sure how to get this from Solr. Moreover, when other facets
