问题 Can any one please point me to some simple examples of semantic tagging and querying semantically tagged documents in MarkLogic ? I am fairly new in this area,so some beginner level examples will do. 回答1: When you say "semantically tagged" do you mean regular XML documents that happen to have some triples in them? The discussion and examples at http://docs.marklogic.com/guide/semantics/embedded are pretty good for that. Start by enabling the triple index in your database. Then insert a test

问题 I am having several documents in STAGING DB. Based on a condition i need to check if the document with same ID exist in FINAL. If it does then i need to replace the multiple nodes of document from STAGING to FINAL and then insert it. DOC from STAGING- <root> <ID>1</ID> <value1>India</value1> <value2>USA</value2> <value3>Russia</value3> <value4>Srilanka</value4> <value5>Europe</value5> <value6>Antartica</value6> <value7>Spain</value7> </root> DOC from FINAL- <root> <ID>1</ID> <value1></value1>

问题 i am doing a cts:element-attribute-range-query and the results from it is working fine. But highlighting is not working for the output result. When i referred the search guide http://developer.marklogic.com/pubs/4.2/books/search-dev-guide.pdf i could see that cts:element-attribute-*-query outputs will not be suitable for cts:highlight function. I am using Marklogic 4.2. My application greatly depends on this highlighted output, Is there any way i can highlight the result output of cts:element

问题 I am trying to update a document in a different Database then my current DB. But it is giving me the below error- XDMP-UPEXTNODES: xdmp:node-replace(fn:doc("/C:/Users/Downloads/abc.csv-0-2")/*:envelope/*:root/*:Status, <Status>1000</Status>) -- Cannot update external nodes I am using the below code- let $temp := for $i in $result let $error := $i/*:envelope/*:ErrorMessage let $status := $i/*:envelope/*:Status return if(fn:exists($i) eq fn:true()) then ( xdmp:invoke-function( function() { xdmp

问题 I can get all the URIs of the documents in a collection by using below XQuery: for $doc in fn:collection("transform") return xdmp:node-uri($doc) But, when I tried to implement this in a Javascript module in MarkLogic, it is getting only last document in the database collection. 'use strict'; declareUpdate() var docs = fn.collection("transform"); for(var doc of docs) { xdmp.nodeUri(doc) } It is not giving all the URIs in the collection, but rather it's only returning the last URI of the

问题 Let's assume I have inserted the below xml in the DB. <root> <name>Dixit</name> <entry> <vol>1212</vol> <title>title1</title> <isbn> <value>123456</value> </isbn> </entry> <entry> <vol>1212</vol> <title>title1</title> </entry> </root> How can I write a cts query which will return me the <entry> nodes with <vol> as 1212 & <title> as title1 & should not have <isbn> element. For the above xml the output should be. <entry> <vol>1212</vol> <title>title1</title> </entry> 回答1: One would normally use

问题 In a relational db you'd have something like "select name, count(1) as c from mytable group by name order by c desc". Basically I want to count how many records contain each name value and get the ones with highest counts first. Is there a way to do a similar thing in Marklogic using the Node.js API? 回答1: Something like this should work: var marklogic = require('marklogic'); var my = require('./my-connection.js'); var db = marklogic.createDatabaseClient(my.connInfo); var vb = marklogic

问题 When I query the SPARQL endpoint for marklogic, I am trying to specify the optimize option: /v1/graphs/sparql?options=optimize%3D2 This results in a 400 error: REST-INVALIDPARAM: (err:FOER0000) Invalid parameter: No configured options: optimize=2" What is the correct syntax to specify this and other options? Related: How can I optimize a SPARQL query that returns optional properties? 回答1: See reference for GET /v1/graphs/sparql. There is an "optimize" parameter you can specify. For example:

问题 I would like to enquire on how data is loaded into this clusters, do I load data separately into each node manually? Or is marklogic able to manage and transfer data among the cluster itself so all I need to do is to load data into a single node? For marklogic to understand and balanced the data between certain forests/databases is there a certain requirement? Such as a need for the forest and database to share the same name or the XDBC server to share the same port number? Finally, I would

问题 I have a database containing XML documents that look roughly as such: <document> <question_item> <question>What is your name?</question> </question_item> <question_item> <question>What is your address?</question> </question_item> ... </document> I want to be able to take a search term and then return a distinct list of questions where that term is found e.g. searching for "name" with the data above, would return one result, "What is your name?". I have successfully implemented this with fn
