Lucene is a fully functional full-text search engine library developed in java. It is suitable for almost any application that requires full-text search, especially cross-platform applications. Lucene is an open-source free project. Luc

This section describes three closely related topics: concurrent access to index files, thread security of IndexReader and IndexWriter, and the lock mechanism Lucene uses to avoid index corruption. Generally, beginners of Lucene have some misunderstandings about these topics. It is very important to understand the content accurately, because when the indexing application serves a large number of different us
Algorithm: There are a lot of books in the library that I have not read, and I would like to use some method to deduce the hypothetical sort results---suppose I read all the books.

Lucene is a full-text search framework, not an application product. Therefore, it is not as useful as www.baidu.com or Google Desktop. It only provides a tool for you to implement these products.
1.2 What Can Lucene doTo answer this question, we m
Lucene OverviewLucene is an open source full-Text search engine toolkit, but it is not a full-text search engine, but rather a full-text search engine architecture that provides a complete query engine and indexing engine for some text analysis engines.There are three types of data:
Structured data (data with fixed format or finite length)
Unstructured data
Semi-structured data
SQL statement queries are generally used for structu
To answer this question, we must first understand the nature of lucene. In fact, lucene has a very simple function. In the end, you give it several strings, and then it provides you with a full-text search service, telling you where the keywords you want to search appear. By knowing this essence, you can use your imagination to do anything that meets this condition. You can index all the news on the site an

Note: Since I was the first to record this kind of video, the imperfect place please forgive me. This series of courses mainly covers three major parts, one is the principle of search engine, the second is the in-depth analysis of
two. So we can get the correlation between the query string and the record in the index by calculating the angle cosine of the query vector with each vector, and then sort it to get the final result.The next introduction to the Lucene file structure will no longer introduce the basic principles of Lucene, the following is a brief introduction of the case may be used in the API. So if you want to know more
When I write an article, I feel that it is difficult to write the title. Sometimes I don't know what the name is. Anyway, I am writing some simple examples about Lucene.
Lucene is actually very simple. It mainly involves two things: Creating indexes and searching.Let's take a look at some of the terms used in Lucene. I am not going to introduce them in detail her
