indexing

问题 *I'm very new to this, I might (probably will?) be talking some jibberish now and then, feel free to correct me ;) I'm playing around with different primary key/index strategies and was wondering about the following. In many cases the choice for a GUID as the primary key is providing the record with unique identification across any database. Now there are some performance issues with using GUIDs as primary key (and default behaviour of using it as the clustered index). There are a few

问题 I'm currently working on a POC that uses Azure Search to make an Angular Front End. I've searched everywhere and am looking for a way to query for the index schema. What do I mean by this? On this page you can use a PUT to create an index using JSON. Is there a way to get this JSON schema back using a GET or using the Azure Portal? I want to be able to populate a NavBar with the facetable fields without having to hard code them. Is this possible? 回答1: You can call Get Index REST API to get

问题 I am trying to create a test analyzer to experiment on analysis on Elastic Search. I have an index created called "mytest" which is available and searchable, but when I try to create a custom analyzer I get below error { "error": "ElasticsearchIllegalArgumentException[Can't update non dynamic settings[[index.analysis.analyzer.content.type, index.analysis.analyzer.content.tokenizer]] for open indices [[mytest]]]", "status": 400 } Now I am not sure on restrictions on updating settings but I

问题 Does anyone know how to add a column index to a server-side processed DataTable? Basically like http://www.datatables.net/examples/api/counter_columns.html, but this example builds the index by client, which is not supported by using the common server-side version. The author Allan gave three hints, but actually I don't get it: Modify the data at the server (the ideal solution) Modify the data as it comes back from the server Edit the draw callback function to take into account the page start

问题 I'm programming in Greenfoot for a school project and I keep getting this error: java.lang.IndexOutOfBoundsException: Index: 1, Size: 1 at java.util.ArrayList.rangeCheck(ArrayList.java:635) at java.util.ArrayList.get(ArrayList.java:411) at Speler.act(Speler.java:60) at greenfoot.core.Simulation.actActor(Simulation.java:583) at greenfoot.core.Simulation.runOneLoop(Simulation.java:541) at greenfoot.core.Simulation.runContent(Simulation.java:215) at greenfoot.core.Simulation.run(Simulation.java

问题 I have a list of different monetary notes and I want to jump to the next index after each loop. How can I do that? I want to make the str dividor equel to [1] after the first loop, then [2], then [3] etc. money_list = [100,50,20,10,5,1,0.5] dividor = money_list[0] while change>0.5: print (change/100) + " X " + [0] change dividor + [0] 回答1: You either need to store the current index in a variable: money_list = [100,50,20,10,5,1,0.5] cur_index = 0 while change>0.5: print (change/100) + " X " +

问题 I was able to port my Neo4j 3.4.0 application to use manual indexes and APOC procedures instead of queries over the indexles relationship properties. Everything is working like a charm except one last thing - I ran into the issue with non-string Lucene range queries. They are not working as expected Lucene query language and numeric range For example: I'm applying the following Lucene query predicate in order to get all inclusive numbers in 2 to 6 range: value:[2 TO 6] and receive the

问题 Every example I've been able to find in the Titan documentation creates indices using the Rexster console. You log in to a single Titan node, create your indices and commit. After a while the whole cluster is aware of the index and it can be used. I am wondering if there are other ways to do this. There are some benefits when creating indices from code e.g. in a Rexster extension: I use ENUMs for property keys and edge labels that offer toString methods I can use on index creation. This way

问题 I currently have a score sheet with tons of rows/columns (product names are on the left, scorers are on the top, and scores are in each cell within this range). What I'm trying to do is create an export/snapshot of only a few of those rows & columns on another sheet in the same workbook. I'm trying to figure out the easiest way to refresh the scores in each of the cells on this worksheet, and so far have arrived at using Index/Match. I want to code it to make this process easy/automated.

问题 I was reading a lot of questions here about getting value of index. I know how to get li on click index number. However, I need to get the li value when the link within it is clicked. <ul> <li><a class=link href="#"></a></li> <li><a class=link href="#"></a></li> <li><a class=link href="#"></a></li> <li><a class=link href="#"></a></li> </ul> $("li a.link").click(function(e) { var i = $(this).index(); alert(i) }); It won't work because it takes the index of a.link not ul li . How can I get
