Tags: mysql full-text index INNODB fulltextThe full-text index fulltext was first used on the InnoDB engine, and recently found a flaw in the design of the Stop Word (stopwords) in the research process.What is a stop word? It means that you do not want users to search for the "master Li Hongzhi", "Falun Dafa" and other words, need to define the stop words in advance, so it will not be searched. But the flaw in design is that you have to define it befo

We would not want these words taking up space on our database, or taking up valuable processing time. As such, we call these words "stop words" because they is useless, and we wish to does nothing with them.

Many of the dictionary resources that are carried in the NLTK are described earlier, and these dictionaries are useful for working with text, such as implementing a function that looks for a word that consists of several letters of EGIVRONL. And the number of words each letter should not exceed the number of letters in egivronl, each word length is greater than 6.To implement such a function, we first call the freqdist function. To get the number of
