I could then search for "test*" and I could quickly find "test", "tested", "testing". I need the list of all endigns that

Reading shorts in 32-bits architectures (for example)

由 浪子不回头ぞ 提交于 2019-12-25 06:43:40
问题 First of all, sorry for my English. I know architectures are very complex and there's a broad sprectrum of situations, but a common generalization is if a computer architecture has 32-bits words, means registers, memory accesses and buses work with words of 32-bits long (but I think there's a lot of variants in current architectures). Ok, let's suppose this is the rule and our architecture is a little-endian one, as x86. In such a case, if we want to read a short int (2-bytes long), the

官方文档位置：https://www.elastic.co/guide/en/elasticsearch/reference/7.5/analysis.html 分词 分词是指将文本转化成一系列的单词（term or token）的过程，也可以叫文本分析 es里称之为Analysis 分词器 分词器是es中专门处理分词的组件,英文为Analyzer ,它的组成如下: Character Filters 针对原始文本进行处理,比如去除html特殊标记符 Tokenizer 将原始文本按照一定规则切分为单词 Token Filters 针对 tokenizer处理的单词就行再加工,比如转小写、删除或新增等处理 分词器-调用顺序 Analyze API es提供了一个测试分词的api接口,方便验证分词效果, endpoint是_ analyze 可以直接指定analyzer进行测试 可以直接指定索弓|中的字段进行测试 可以自定义分词器进行测试 直接指定Analyzer进行测试，接口如下： POST _analyze { "analyzer":"standard", //分词器,standard是es默认分词器，如果字段里没有指定分词器，会默认使用standard "text":"hello world!" //测试文本 } 输出： { "tokens": [ { "token":

How to write string to file in different lines in C

由 ╄→гoц情女王★ 提交于 2019-12-24 20:13:57
问题 I have program that replaces a word in a file with another one, but in the new file the lines are all written as one line, not in different lines and paragraphs as required. I tried adding '\n' at the end of each line I am reading from the original file, but it is not working. This is my code: int main() { FILE *f1, *f2; char word[MAX], fname[MAX]; char s[MAX], replace[MAX]; char temp[] = "temp.txt", *p1, *p2; printf("Enter your input file name:"); fgets(fname, MAX, stdin); fname[strlen(fname

Word boundary does not work inside brackets in regex [duplicate]

由 落花浮王杯 提交于 2019-12-24 13:51:20
问题 This question already has an answer here : Regex word boundary alternatives inside parentheses does not work? (1 answer) Closed 5 years ago . I have noticed that the word boundary \bword\b does not work inside brackets when doing a preg_replace() in PHP. Specifically, I'm trying to exclude the full word > (which stands for > in HTML), but since the word boundary does not trigger inside brackets as in [^\b>\b] , any of those characters by itself, like g or & , will be detected as a non-match.

Counting words in Ruby with some exceptions

由 ≡放荡痞女 提交于 2019-12-24 13:42:34
问题 Say that we want to count the number of words in a document. I know we can do the following: text.each_line(){ |line| totalWords = totalWords + line.split.size } Say, that I just want to add some exceptions, such that, I don't want to count the following as words: (1) numbers (2) standalone letters (3) email addresses How can we do that? Thanks. 回答1: You can wrap this up pretty neatly: text.each_line do |line| total_words += line.split.reject do |word| word.match(/\A(\d+|\w|\S*\@\S+\.\S+)\z/)

1.分分钟扒一个网页下来 怎样扒网页呢？其实就是根据URL来获取它的网页信息，虽然我们在浏览器中看到的是一幅幅优美的画面，但是其实是由浏览器解释才呈现出来的，实质它是一段HTML代码，加 JS、CSS，如果把网页比作一个人，那么HTML便是他的骨架，JS便是他的肌肉，CSS便是它的衣服。所以最重要的部分是存在于HTML中的，下面我们就写个例子来扒一个网页下来。 1 import urllib2 2 3 request = urllib2.Request("http://www.baidu.com") 4 reponse = urllib2.urlopen(request) 5 6 print reponse.read() 1 var _chrome_37_fix = document.createElement("style"); 2 _chrome_37_fix.type="text/css"; 3 _chrome_37_fix.setAttribute("data-for","result"); 4 _chrome_37_fix.innerHTML = ".t,.f16,#kw,.s_ipt,.c-title,.c-title-size,.to_zhidao,.to_tieba,.to_zhidao_bottom{font-size:15px;} .ec-hospital

Div Editable and More… More

由 旧巷老猫 提交于 2019-12-23 02:34:44
问题 Well, I need to replace a word, in a div contentEdible property on, by the same word but formatted... Like this: <div> My balls are big </div> To this (replace the word: balls): <div> My <font style="color:blue;">balls</font> are big </div> In a contentEditable this happens dinamically, while the user type the text the replacements happens. I think that a simple event onkeydown, onkeyup, or onkey press, can solve this part. But, the trouble is with the caret, that after all that i tryed, it

What is the regular expression for a Spanish word?

由 痴心易碎 提交于 2019-12-22 05:39:17
问题 Regular expression languages use \B to include A..Z, a..z, 0..9, and _, and \b is defined as a word boundary. How can I write a regular expression that matches all valid Spanish words, including characters such as: á, í, ó, é, ñ, etc.? I'm using .NET. 回答1: Use a Spanish locale and make your regex locale-sensitive. 回答2: Your regex system should have something equivalent to Python's re.L (aka re.LOCALE ) to make a regex locale-dependent, so that what's a word-character and what isn't changes
