different from version 3. x. First, let's take a look at how to obtain a quasi-real-time search Reader instance. We all know that Lucene-based applications generally use the Lucene-based Writer, Reader, and Searcher sharing solutions for performance and other reasons, we are no exception here: IndexPathname = "D:/aproject/xincaigu/work/index"; analyzer = new MMSegAnalyzer (); IndexWriterConfig iwc = new IndexWriterConfig (Version.

Indexwriterconfig and IndexWriter:Indexwriterconfig, known from the class name, is a class that holds parameter configurations for generating IndexWriter. Like what:Indexwriterconfig IWC = new Indexwriterconfig (luceneanalyzer); Iwc.setopenmode (openmode.create); Setopenmode (...) sets the way IndexWriter is opened.Of course there are more parameter settings, you can refer to this article Oh.

And then in the console for some input operations,Query a string of unordered random strings, the result is 0 results; query ' string ' because two files have a string, so query to 2 results, and paging.In this case, the simple use of Lucene demo runs out, you can see the results of the search very intuitively.
