solr

问题 I am new to Apache solr, can someone please explain the meaning of following terms with examples :- Solr Core Solr Collection Logical vs Physical index Sharding I went through various blog posts but i am not able to understand. 回答1: The terminology is used a bit haphazardly, so you'll probably find texts that use a few of these terms interchangeably.

问题 I have the following model for a type of document in Solr 5: 1 document per entity entity has about 100 single valued attributes entity has 1 multi valued attribute uuids_scores , which contains a value like "123_456", being the first part (123) the user id and the second part (456) a stored score I keep for each user. an entity can have about 100 k uuids_scores values.

问题 I am trying to add a new document in the solr server. My Code $.ajax({ type: "POST", url: "http://192.168.10.113:8080/solr/update/json?commit=true", data: { "add": { "doc": { 'id': '19990' } } }, dataType: 'jsonp', crossDomain: true, jsonp: 'json.wrf', success: function (data) { alert(data); }, failure: function (errMsg) { alert(errMsg); } }); My Solr server is hosted in different domain so i wrote dataType: 'jsonp', crossDomain: true, jsonp: 'json.wrf', to over come from cross domain problem

问题 I'm trying to send my inline JSON file to my Solr Database, but I'm having a problem with my nested objects. I have two nested objects inside my _source object which are media_gallery and stock . Before my upload used to crash, but I managed to upload it after a few corrections, but my media_gallery and stock are added as separate objects therefore instead of having the original 1000 objects I get 3000 objects in my Solr DB after my upload. I'm currently using this command to upload my JSON

问题 I'm exploring various options for a search engine for our rails-app/data. I was able to make sunspot/solr work and am currently exploring ElasticSearch as an alternative but couldn't get the same thing(scoping/filtering) to work under ES. I would like to filter/scope objects as described in the "Scoping" section in 'https://github.com/sunspot/sunspot'. I have an active record class 'Product'. class Product < ActiveRecord::Base ... include Tire::Model::Search include Tire::Model::Callbacks

问题 I want to optimise my Solr engine. I don't want ranked results. I just want all docs which match my query is there any way I can remove it . So that retrieving data improves ? 回答1: There is no need to remove relevancy ranking to achieve what you want. By setting the rows parameter to the same number as the numfound you will retrieve all documents matching your query. http://url-to-some-server/solr/select?q=somequery&rows=200 if you want the documents sorted in another way than by relevance,

问题 I want to post and index a PDF document while also updating a custom field I created. Basically, I want users to be able to enter tags before they upload a document. I added a multiValued "tags" field to my managed-schema file: <field name="tags" type="string" multiValued="true" indexed="true" required="true" stored="true"/> I have tried the curl commands for posting data, but they do not work for me. So far, this is the only command that I can post with that works: java -Dauto -Dc=NameOfCore

问题 I'd like to write a custom tokenizer in Apache Solr 3.6, that will try to identify certain types of tokens and depending on their type search on different fields. For example, if the search were for 2in screw , I would have the custom tokenizer identify that 2in refers to a value and unit of measure and that screw refers to a category. I would then want to limit the search to "in" in the measure field and "screw" in the category field. I realize that this can be done be externally breaking

问题 The following query works well for me http://...:8983/solr/vault/select?q=White&defType=edismax&qf=VersionComments+VersionName returns all the documents where version comments includes White I try to omit the qf containing the fields names : In solr config I write <requestHandler name="/select" class="solr.SearchHandler"> <!-- default values for query parameters can be specified, these will be overridden by parameters in the request --> <lst name="defaults"> <str name="echoParams">explicit<
