My friend she told me last week that FTK could not "see" keywords in a plain text files when doing index search. That's very interesting. I used to trust the search results of FTK, and I think there must be something wrong . I have to do a test…
Some of my friends ask me a question: "Does FTK index search support regular expression?" They just participated in FTK Bootcamp last month, and they're trying to spend more time with FTK now. The answer is "Yes". FTK index search supp…
I used to conduct raw search in EnCase v6, and I'd like to see if EnCase v7 raw search could hit keywords inside compound files or not. You won't believe it~search results is 0 but those keywords do exist inside compound files...Let my show you my te…
结合网上的资料,抄袭了几张图,记录下. 1.solrcloud-collection/shard/replica 1.Replica.Leader是core的角色,在index.search的过程中作用不同. 2.不同shard尽量分布在不同的solr节点上.solr上的core尽量分布“均匀”,确保负载平均. 2.solrCloud-index 1.将index请求发送到任意core上. 2.如果core是Replica,则转发到同shard的Leader上. 3.判断index到哪个分片上(…

elastic4s是elasticsearch一个第三方开发的scala语言终端工具库(Elastic4s is a concise, idiomatic, reactive, type safe Scala client for Elasticsearch.).scala用户可以用elastic4s提供的DSL用编程代码形式来构建ES服务请求.与字符型json文本直接编写请求不同的是:在编译DSL编写的ES服务请求时可以发现无论是语法上或者语意上的错误.一般来讲:elastic4s的程序流程相…
elasticsearch的config文件夹里面有两个配置文件:elasticsearch.yml和logging.yml,第一个是es的基本配置文件,第二个是日志配置文件,es也是使用log4j来记录日志的,所以logging.yml里的设置按普通log4j配置文件来设置就行了.下面主要讲解下elasticsearch.yml这个文件中可配置的东西. cluster.name: elasticsearch配置es的集群名称,默认是elasticsearch,es会自动发现在同一网段下的es,…

一.简介 ElasticSearch和Solr都是基于Lucene的搜索引擎,不过ElasticSearch天生支持分布式,而Solr是4.0版本后的SolrCloud才是分布式版本,Solr的分布式支持需要ZooKeeper的支持. 这里有一个详细的ElasticSearch和Solr的对比:http://solr-vs-elasticsearch.com/ 二.基本用法 Elasticsearch集群可以包含多个索引(indices),每一个索引可以包含多个类型(types),每一个类型包含…
在js中,经常会遇到在函数里调用其它函数的情况,这时候会有 fn() 这种调用方式,还有一种是 return fn() 这种调用方式,一些初学者经常会一脸萌逼地被这两种方式给绕晕了.这里用一个优雅的面试题来分析一下两种方式的不同之处. var i = 0; function fn(){ i++; if(i < 10){ fn(); }else{ return i; } } var result = fn(); console.log(result); 这是一道隐藏了坑的面试题,看似很简单,大部分…
简介 链表就是链式存储数据的一种数据结构.双向链表每个数据存储都包含他的前后数据节点的位置信息(索引/指针). class DSChain<T> { //使用栈来进行废弃空间回收 private DSStack<int> _recycle; //数据需要三个数据来存储内容,分别存储前后节点索引和数据本身 private int[] _prev; private T[] _ds; private int[] _next; //链表头尾的索引,跟踪表尾主要方便LRU使用 private…
支持多种存储引擎是众所周知的MySQL特性,也是MySQL架构的关键优势之一.如果能够理解MySQL Server与存储引擎之间是怎样通过API交互的,将大大有利于理解MySQL的核心基础架构.本文将首先介绍MySQL的整体逻辑架构,然后分析MySQL的存储引擎API并介绍如何编写自己的MySQL存储引擎. MySQL逻辑架构 MySQL作为一个大型的网络程序.数据管理系统,架构非常复杂.下图大致画出了其逻辑架构. Connectors MySQL首先是一个网络程序,其在TCP之上定义了自己的应…
