Lucene In Action 1.5, a vast majority of translation and understanding, bilingual comparison■ IndexWriter IndexWriter is the central component of the indexing process. This class creates A new index and adds documents ents to an existing index. You can think of Index- Writer as an object that gives you write access to the index but doesn't let you read Or search it. Despite its name, IndexWriter isn't the only class that's used to modify An index; section 2.2 describes how to use the Lucene API

usage: will become very useful in LINQ queries. c# iteration structure: For loops, like for loop usages in C and C + +, we can create complex termination conditions, construct an infinite loop, and use the Goto, continue, break keywords. Foreach/in loop: The C#foreach keyword allows you to iterate through all the items in the array, without having to test the array's on-line. When using Var in a foreach structure, the compiler can accurately determine the exact type of the type. While and Do/wh

. now HttpApplication needs to initialize the request processing pipeline to handle the response operations of pages of type ASP. NET WebForm or ASP. It performs its corresponding Init method on each of its httpmodule by reading the information about HttpModule in the Web. config configuration file and passing it to the collection of HttpModule. Next , complete the registration of the HttpApplication 19 pipeline events . All you need now is to invoke the execution method corresponding to each ev

The most important of the naming rules is create rule, which is officially stated as follows:There is a important distinction between Get, and Copy and Create, in names of functions that return values. If You use a Get function, you cannot is certain of the returned object ' s life span. To ensure the persistence of such a object can retain it (using the Cfretain function) or, in some cases, copy it. If you use a Copy or Create function, you is responsible for releasing the object (using the Cfr

the string buffer contains a sequence of characters that does not exceed this capacity, there is no need to allocate a new array of internal buffers. If an internal buffer overflows, this capacity is automatically incremented.Starting with JDK 5, this class complements the equivalence class used by a single thread, StringBuilder. The StringBuilder class should usually be preferred over this class because it supports all the same operations, but it is faster because it does not perform synchroni

Java core programming-byte stream of IO stream (2), javaio 1. byte stream A 1.1-byte stream is a stream that operates byte. Byte streams can operate on any data, such as media data, music, movies, and images. Of course, they can also operate on characters. Byte stream is based on byte stream, we know that a byte is 8 binary bits, a byte corresponds to an English character in the UTF-8, people found that usi
