Lucene is a high-performance Java full-text retrieval toolkit that uses the Inverted File index structure. This structure and corresponding generation Algorithm As follows: 0) There are two Article 1 and 2 Article 1: Tom lives in Guangzhou, I live in Guangzhou too. The content of article 2 is: he once lived in Shanghai. 1) Because Lucene is based on keyword indexing and query, we need to obtain the keywords of the two articles. Generally, we need

As a search, our traditional method (positive index) starts from the key point, and then finds the specific information that can meet the search conditions in the Key Point information, both search for value through key. Lucene uses inverted indexes to search for keys. In Chinese full-text search, value is the word to be searched, and the place where all words are stored is called a dictionary. Key is the document label list. (You can find the documen

So we have to start from the initial state to construct the three states it departs from. Then these three states can be compared with the state of the backward push.#include #includestring.h>#includeusing namespacestd;intt,a[5],b[5];intMain () {scanf ("%d",t); while(t--) {scanf ("%d %d%d%d%d%d", a[1],a[2],a[3],b[1],b[2],b[3]); intok=0; Sort (a+1, A +4); Sort (b+1, B +4
