solr

问题 I have text field. And for given query I want to find all documents that contains indexed field values. query.contains(document.field_name) Examples: 1. field_name:"a b" 2. field_name:"a b c" For query "a b d" I want to find only first item. Not efficient way to do this is basically generate all substrings of query and index field as a string. Is it possible to implements such requirements in Solr using existen functionality? If not what is the most efficient algorithm/way to do this? PS.

问题 We have a large number of Solr cores, which all share the same fields but have differing definitions for certain field types (e.g. for different languages). For instance, in the following example, I have a full_text field of type text that exists in two different cores but I apply different filters to the text field in each core. Core 1 <fields> <field name="full_text" type="text" indexed="true" /> </fields> <types> <fieldType name="text" class="solr.TextField"> <analyzer type="index">

问题 I am trying to index a document to a specific collection in solr. The collection name is 'program'. I am using spring data solr. I am getting the below error when trying to save the document: HTTP ERROR 404 Problem accessing /solr/update. Reason:Not Found My assumption is that the annotation @SolrDocument is not recognized. spring-data-solr is trying to post the document to /solr/update whereas it should try to post it to /solr/program/update.However I am not sure how to prove it or fix it.

问题 I'm very new to Solr. I succeeded in indexing data from my sql database via DIH. Now I want to import xml files and index them also via DIH but it just won't work! My data-config.xml looks like this: <dataConfig> <dataSource type="FileDataSource" encoding="UTF-8" /> <document> <entity name="dir" processor="FileListEntityProcessor" baseDir="/bla/test2" fileName=".*xml" stream="true" recursive="false" rootEntity="false"> <entity name="PubmedArticle" processor="XPathEntityProcessor" transformer=

问题 I want to filter the Sunspot search results with with(:is_available, true) . This is working with the User model, but I can't make it work with the Itinerary model. app/controllers/search_controller.rb: class SearchController < ApplicationController before_filter :fulltext_actions private def fulltext_actions @itineraries = do_fulltext_search(Itinerary) @users = do_fulltext_search(User) @itineraries_size = @itineraries.size @users_size = @users.size end def do_fulltext_search(model) Sunspot

问题 I intend to make a niche search engine. I am using apache-nutch-1.6 as the crawler and apache-solr-3.6.2 as the searcher. I must say there is very less updated information on web about these technologies. I followed this tutorial http://wiki.apache.org/nutch/NutchTutorial and have successfully installed apache and solr on my ubuntu system. I was also successful in injecting seed url to webdb and perform the crawl. Using solr interface at http://localhost:8983/solr/admin , I can also query the

问题 Following Solr documentations (https://cwiki.apache.org/confluence/display/solr/Function+Queries and others) I should just put idf(fieldname, 'term') as I do with termfreq(fieldname, 'term') in the field list. However, whenever I try this I get an exception as: org.apache.solr.client.solrj.SolrServerException: No live SolrServers available to handle this request By looking at the logs I could find: null:java.lang.UnsupportedOperationException: requires a TFIDFSimilarity (such as

问题 Running multi-core Solr under Tomcat 6.0 /Win 2008 Server and ASP.NET queries via SolrNet. One of the cores is huge i.e. ~25 million documents (~20 GB disk-space) and several fields. The other 3 cores are much smaller (few gigs each). After a couple of queries to the large index, Solr slows down dramatically and stops responding i.e. can't even open admin console. If I restart tomcat, things again works ok for a few more queries and then molasses to stop. I have checked the machine RAM and

问题 I read at some point something explaining what to do to have Lucene/Solr give a better score if my queried word was found at the beginning of the description I indexed. Cannot find it anymore on the net. Anybody has the links handy ? Thank you. 回答1: Payloads could help you do that. Actually, payloads let you give an arbitrary boost to any token of your token stream, so you can boost depending on anything: the position in the stream, the font weight, whether the token contains capital letters,
