Sensitive words, text filtering is an essential function of a website, how to design a good, efficient filtering algorithm is very necessary. Some time ago I a friend (immediately graduated, contact programming soon) want me to help him to see a text filter thing, it says retrieval efficiency is very slow.

? We will naturally think of the word-base segmentation method, that is, we get a thesaurus, which lists most of the words, we divide the sentence in a certain way, when the resulting words and words in the Thesaurus match, we think this segmentation is correct. So the process of cutting words turns into a matching process, and the most simple way to match is the forward maximum matching and inverse maximum
longer.To solve the problem, first analyze the three parser of the word breaker. StandardAnalyzer and Chineseanalyzer are the sentences in a single word, that is, "milk is not as good as juice," they will be cut into "milk is not as good as juice", and Cjkanalyzer will be cut into "cow grandma, if the juice is good to drink." 。 This also explains why the search for "juice" can match this sentence.There are at least two drawbacks to the above participle: mismatched matching and large index file.
