To figure out how the relevance of the document search was calculated behind elastic search, I decided to do my own experiments to exploreThis blog is a good one to say.http://blog.csdn.net/dm_vincent/article/details/42099063And the blog itself is just translating official documentsHttps://www.elastic.co/guide/en/elasticsearch/guide/current/scoring-theory.htmlI'm going to test it.When searching for a document, a combination of the following underlying

Simple implementation of javascript elastic movement effect, javascript Elasticity This article describes how to implement javascript elastic movement. We will share this with you for your reference. The details are as follows: Principle of elastic movement: acceleration, deceleration, and friction The running effect is as follows: The instance code is as follow

This algorithm is suitable for the common two-dimensional fully elastic collisions, supports the collision of the heart (positive touch) and non-heart collision (oblique touch), regardless of the mechanical energy loss during the collision, regardless of the surface friction and recovery coefficients. /** This is an object of its own, SP is the object of the collision* THIS.M Quality* THIS.R radius* THIS.VX Horizontal speed* This.vy Vertical spee

Experimental environment ES version: 5.3.0 Spring BT version: 1.5.9 First of all, of course you need to install the elastic search environment, it is best to install the visual plug-in Elasticsearch-head to enable us to visually view the data.Of course, this section can refer to my post:"Centos7 on Elastic search installation Pits Kee"Https://www.jianshu.com/p/04f4d7b4a1d3My ES is installe

The principle of elastic sliding A large slide is not a number of minor slides and is completed within a time period. A better user experience There are many ways to implement it, including using scroller, animation, and latency strategies. Using handler to achieve elastic sliding The effect can see the button buttons sliding. Note that this changes the contents of the view. You can try to remove the o

The dataflow type is used to process data streams, and it provides 2 job types, namely Throughputdataflow and Sequencedataflow. The corresponding abstract class needs to be inherited. The script type is used for processing scripts and can be us

. _index is a virtual field that does not really add to the Lucene index. 2._type: The type name of the document, which can be queried, aggregated, scripted, and sorted according to _type. 3._ID: Document unique ID; 4._UID: Combination ID, composed of _type and _id; 5._source: The original JSON data for the document, where you can get the contents of each field. The default _source field is on, or it can be closed: 6._all: Fields are stitched together

In the Android development of the ListView, ScrollView used very high frequency, but a good application we can see that the effect is not so rigid, Android native ListView and ScrollView can not meet this requirement, Therefore, this flexible view is needed for development. In peacetime development, I collected the top and bottom pull with elastic listview and ScrollView, here to share to everyone, there is a need to use can be downloaded directly.Ela

Main TopicGiven a line, the length is l to indicate the interval [0, l]. To start placing n individuals on a straight line, each person has an initial position of POS (denoted by the distance from the top of the line at point 0) and the initial direction dir (' P ' or ' p ' denotes walking toward the endpoint L, ' n ' or ' n ' means walking toward endpoint 0), and then all the people start walking in their direction at the same If you go to endpoint 0 or end L, the person falls down, and if two

Internet Explorer in IE8, people seem to have abandoned it and simply accept float as the actual solution. Introduction to the elastic box model layout module (aka flex box) There is a hidden weapon: the elastic box model layout module that most people seem to have overlooked. It provides: And other columns. Independent element sequence. Specifies the relationship between elements. Flexible dimensions
