Solr/Lucene Scorer

由 微笑、不失礼 提交于 2019-12-17 10:46:05
问题 We are currently working on a proof-of-concept for a client using Solr and have been able to configure all the features they want except the scoring. Problem is that they want scores that make results fall in buckets: Bucket 1: exact match on category (score = 4) Bucket 2: exact match on name (score = 3) Bucket 3: partial match on category (score = 2) Bucket 4: partial match on name (score = 1) First thing we did was develop a custom similarity class that would return the correct score

WSO2 API Manager issues with solr

问题 I have setup a new setup of WSO2 API Manager integrated with WSO2 Identity Server.

How can I tell Solr to return the hit search terms per document?

由 白昼怎懂夜的黑 提交于 2019-12-17 09:47:13
问题 I have a question about queries in Solr. When I perform a query with multiple search terms that are all logically linked by OR (e.g. q=content:(foo OR bar OR foobar) ) than Solr returns a list of documents that all matches any of these terms. But what Solr does not return is which documents were hit by which term(s). So in the example above, what I want to know is which documents in my result list contains the term foo etc. Given this information I would be able to create a term-document

Is Solr 4.0 capable of using 'join" for multiple core?

由 两盒软妹~` 提交于 2019-12-17 09:31:26
问题 I notice Solr 4.0 has introduced 'join' feature for documents having relationships. this is great, however, I notice examples given by http://wiki.apache.org/solr/Join are for single core which all documents are in single index. Does anybody know if I can use 'join' for multiple core? 回答1: This comment says it's possible by using: {!join from=fromField to=toField fromIndex=fromCoreName}fromQuery I tried it myself, and here's a more detailed example: Have two cores brands {id,name} products

Search Engine - Lucene or Solr

由 时间秒杀一切 提交于 2019-12-17 08:12:28
问题 We need to integrate a search engine in our Product Catalog management software. the catalog is expected to have more than 4-5 mn. records with relational data spread over several tables. Our dev platform is Asp.Net 3.5 and we have done some pre-liminary work on Lucene, found it to be good. However, we just came to know of Solr and was looking for some practical tips to compare Lucene & Solr from implementation, timeline, regular maintenance, performance, features perspective.

Solr index vs stored

由 浪尽此生 提交于 2019-12-17 06:34:23
问题 I am a little confused as to what the behaviour of the index and stored attibutes of the Solr fields is. For example if I have the following in the Schema.xml <field name="test1" type="text" indexed="false" stored="false" required="false" /> Will the field test1 be not stored in the Solr document even if I create a document with that field in it and set a value to that field and commit the document to Solr. As I have the stored=false attribute, does it mean that the value of the field is lost
