Say you have the following nested document. { "key1" : "value1", "key2" : { "key21" : "value21", "key22" : "value22" } } If you mean to make query on the nested documents then you can access the embedded object using the following java code.

由 倖福魔咒の 提交于 2020-01-03 10:26:39
问题 I am wondering a little when I look at this code: // Get the screen height and width var maskHeight = $(document).height(); var maskWidth = $(window).width(); ... // Get the window height and width var winH = $(window).height(); var winW = $(window).width(); What is the difference between $(document).height(); and $(window).height(); ? 回答1: $(document).height is the inside area of the viewport, essentially from the bottom of your toolbar/url bar to your status bar/bottom scroll bar/bottom of

Getting the path & filename of the open document in any Windows application

由 情到浓时终转凉″ 提交于 2020-01-03 05:21:13
问题 Goal Let me start with my final vision of what I'd like to be able to do first: In Windows, I'd like to be able to use a global keyboard shortcut that I define (say, Ctrl + Alt + C ) to copy the full path and filename of the open document in the foreground application to the clipboard. This would be useful to, for example, be able to subsequently paste the path & filename into an "Open File" dialog in an email client to attach that document to an email, without having to manually browse to

Solr, block updating of existing document

由 别等时光非礼了梦想. 提交于 2020-01-02 06:40:34
问题 When a document is sent to solr and such document already exists in the index (by its ID) then the new one replaces old one. But I don't want to automatically replace documents. Just ignore and proceed to the next. How can I configure solr. Of course I can query solr to check if it has the document already but it's bad for me since I do bulk updates and this will complicate the process and increase amount of request. So are there any ways to configure solr to ignore duplicates? 回答1: You can

How to find the page number from a paragraph using OpenXML?

由 余生颓废 提交于 2020-01-01 11:31:46
问题 For a Paragraph object, how can I determine on which page this is located using the Open XML SDK 2.0 for Microsoft Office ? 回答1: It is not possible to get page numbers for a word document using OpanXml Sdk as this is handled by the client (like MS Word). However if the document you are working with is previously opened by a word client and saved back, then the client will add LastRenderedPageBreak to identify the page breaks. Refer to my answer here for more info about LastRenderedPageBreak s

由 南笙酒味 提交于 2019-12-31 13:46:05
问题 I have a large collection of half-page sized PDF cut-sheets that are held in a folder on my Linux server. A user to the site will want to create a booklet from a subset of these. The booklet will be bound therefore the even pages of the collection will want more margin on the right side and the odd pages will want more margin on the left side. There can be up to 200 pages in a collection out of a universe of 500 pages so I don't want to regenerate each page to set the margin of it. It would

问题 I'm doing a job for a guy with a site online. It's an alien site to me, and I'm slowly working through the strange code.

How can I easily set the document_root reference to what it should be (just locally though, don't really want to mess with the site files, as
