Lucene term boosting with sunspot-rails

阅读更多关于 Lucene term boosting with sunspot-rails

问题 I'm having an issue with Lucene's Term [Boosting][1] query syntax, specifically in Ruby on Rails via the sunspot_rails gem. This is whereby you can specify the weight of a specific term during a query, and is not related to the weighting of a particular field. The HTML query generated by sunspot uses the qf parameter to specify the fields to be searched as configured, and the q parameter for the query itself. When the caret is added to a search term to specify a boost (i.e. q=searchterm^5) it

Solr: Retrieve non-stored fields from external data source

阅读更多关于 Solr: Retrieve non-stored fields from external data source

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

阅读更多关于 MySql Full text or Sphinx or Lucene or anything else?

问题 I am currently using MySql and have a few tables which i need to perform boolean search on. Given the fact my tables are Innodb type, I found out one of the better ways to do this is to use Sphinx or Lucene. I have a doubt in using these, my queries are of the following format, Select count(*) as cnt, DATE_FORMAT(CONVERT_TZ(wrdTrk.createdOnGMTDate,'+00:00',:zone),'%Y-%m-%d') as dat from t_twitter_tracking wrdTrk where wrdTrk.word like (:word) and wrdTrk.createdOnGMTDate between :stDate and

Solr: Partial email search with exact match

阅读更多关于 Solr: Partial email search with exact match

问题 I'm currently developing a search, where users need to search people by their first name, last name or their email. For the search I'm using Solr 4.0.0-ALPHA and edismax query. The problem I am having is that if a user were to search user with a partial email I would need to return only the matches that match exactly that partial email query. For example query: lastname@gmail should return only users that match "lastname@gmail". For example: firstname.lastname@gmail.com but now instead it

Sorting on multivalued field in Solr

阅读更多关于 Sorting on multivalued field in Solr

问题 I know multivalued field sorting is not supported in Solr . But Is there any way we can sort multivalued field in Solr. I have two documents with field custom_code and values are as below, Doc 1 : 11, 78, 45, 22 Doc 2 : 56, 74, 62, 10 When I sort it in ascending order the order should be , Doc 2 : 56, 74, 62, 10 Doc 1 : 11, 78, 45, 22 Here Doc 2 will come first because it has smallest element 10 (which is greater that 11 of doc 1). How can we achieve this in Solr. What is the easiest way? 回答1

搜索引擎选择： Elasticsearch与Solr

【推荐】2019 Java 开发者跳槽指南.pdf(吐血整理) >>> Elasticsearch简介 * Elasticsearch是一个实时的分布式搜索和分析引擎。它可以帮助你用前所未有的速度去处理大规模数据。它可以用于全文搜索，结构化搜索以及分析，当然你也可以将这三者进行组合。 Elasticsearch是一个建立在全文搜索引擎 Apache Lucene™ 基础上的搜索引擎，可以说Lucene是当今最先进，最高效的全功能开源搜索引擎框架。但是Lucene只是一个框架，要充分利用它的功能，需要使用JAVA，并且在程序中集成Lucene。需要很多的学习了解，才能明白它是如何运行的，Lucene确实非常复杂。 Elasticsearch使用Lucene作为内部引擎，但是在使用它做全文搜索时，只需要使用统一开发好的API即可，而不需要了解其背后复杂的Lucene的运行原理。当然Elasticsearch并不仅仅是Lucene这么简单，它不但包括了全文搜索功能，还可以进行以下工作: 分布式实时文件存储，并将每一个字段都编入索引，使其可以被搜索。实时分析的分布式搜索引擎。可以扩展到上百台服务器，处理PB级别的结构化或非结构化数据。这么多的功能被集成到一台服务器上，你可以轻松地通过客户端或者任何你喜欢的程序语言与ES的RESTful API进行交流。
