自定义mapping的api PUT test_index { "mappings": { #mappings关键字 "doc": { #type "properties": { #字段名称和类型的定义 "name":{ #字段名 "type": "keyword" #字段类型 }, "message":{ "type": "text" }, "age":{ "type": "integer" } }}}} mapping中字段类型一旦设定后 禁止直接修改。因为lucene实现的倒排索引生成后不允许修改 除非重建索引映射,然后做reindex操作。 1,POST _reindex { "source": {"index":"旧索引"}, "dest": {"index":"备份索引"} } 2,删除旧索引 3,新索引建立mapping 4,POST _reindex { "source": {"index":"备份索引"}, "dest": {"index":"新索引"} } View Code Field datatypes 字段的数据类型 核心数据类型 字符串类型: text(分词),keyword(不分词)一个用于全文检索,一个用于聚合和排序。 数值型: long,integer,short,byte,double,float,half_float,scaled_float

python的正则表达式模块re 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 import re match_object = re. compile (r"") result = re.match(match_object, "resource string" ) result = re.search(match_object, "resource string" ) result = re.findall(match_object, "resource string" ) # 注意区别 match_object.match( "resource string" ).group() match_object.search( "resource string" ).group() match_object.findall( "resource string" ) #上下两种方式任选一种,findall是返回列表 print result.group() match()与search()的区别: match是从源字符串的头部开始,仅当从第一个字符开始匹配成功,才能从字符串中匹配到目标字符串 search是从源字符串任意位置开始匹配 match和search的共同点是一旦匹配成功就返回,因而只会从源字符串中成功匹配一个目标字符串 findall

问题 I need to filter a collection of strings based on a rather complex query - in it's "raw" form it looks like this: nano* AND (regulat* OR *toxic* OR ((risk OR hazard) AND (exposure OR release)) ) An example of one of the strings to match against: Workshop on the Second Regulatory Review on Nanomaterials, 30 January 2013, Brussels So, I need to match using AND OR and wildcard characters - so, I presume I'll need to use a regex in JavaScript. I have it all looping correctly, filtering and

Scala match decomposition on infix operator

时光总嘲笑我的痴心妄想 提交于 2019-12-22 04:08:39
问题 I'm trying to understand the implementation of List s in Scala.

The important thing is that somewhere there is an object named :: which
