问题 I'm going nuts trying to figure out how to get the Data Import Handler's splitBy construct to work. I was expecting it to split the input column into a multivalued field. Here's a test case to reproduce the problem: import java.io.File; import java.io.IOException; import java.sql.SQLException; import static org.junit.Assert.*; import javax.sql.DataSource; import org.apache.commons.dbutils.QueryRunner; import org.apache.commons.io.FileUtils; import org.apache.solr.client.solrj.SolrQuery;

问题 I have a server set up with several Rails apps, two of which are using Solr Sunspot. However, Solr is returning irrelevant results for a given search, and I believe the problem boils down to not having separated Solr/Sunspot to handle two Rails apps. I have this in one app: class Article < ActiveRecord::Base searchable do text :title, :boost => 2.0 text :body do strip_tags body end time :created_at end end and this in the other: class Article < ActiveRecord::Base searchable do text :title,

问题 We are looking to have a Solr 4.9 setup where we have a very simple crawler wipe out and load up a "crawler" core then trigger a copy of the data over to "search" core when the crawl is done. The purpose of this is that our crawler is VERY simple, and doesn't really track documents in a way that would be conducive to doing updates and deleted. Basically, the crawler will be wiping out the entire "crawler" core, ripping though about 50k documents (committing ever 1000 or so), and then trigger

问题 I am rather new to SolR. I would like to use multiple tokenizers. I am using the standard tokenizer so that words get split via \t, space, comma, etc. Now I would like to use an additional tokenizer. If there is the word "cowshed" I would like it to become "cow" and "shed". There are only I few words which are common to the search index which I would like to split. Therefore I planned using the regex tokenizer. However I get an error message when I try to ("multiple tokenizers at xml root").

问题 I have an application where it search images that are stored in the database and displays the result (with pagination). Currently every time the next page is loaded our whole site is reloaded. Hence, our site is noticeably sluggish. I was looking into iStockPhoto and see that only the images content is loaded and their performance is much better than mine. I am using Solr (which to me seems slow.. anything I'm missing? I thought Solr is supposed to be quick. Haha) to store and retrieve images

问题 In the documentation of php-Apache Solr PHP extension, it is mentioned that "It is compatible with both versions 1.3 and 1.4 of Apache Solr."

问题 I need to extract numeric values from strings like "£17,000 - £35,000 dependent on experience" ([0-9]+k?[.,]?[0-9]+) That string is just an example, i can have 17k 17.000 17 17,000 , in every string there can be 0,1 or 2 numbers (not more than 2), they can be everywhere in the string, separated by anything else. I just need to extract them, put the first extracted in a place and the second in another. I could come up with this, but it gives me two matches (don't mind the k?[,.] , it's correct
