[英]elasticsearch extract keywords from text
I have more than 4000 keywords I want to indexed by elasticsearch.我有超过 4000 个关键字要由 elasticsearch 索引。 I want to pass it the text and extract the existing keywords.我想将文本传递给它并提取现有的关键字。 The first problem is that when I pass a few numbers it works but when I pass a lot of keywords it extracts words that are not in the text.第一个问题是,当我传递几个数字时它可以工作,但是当我传递很多关键字时,它会提取文本中没有的词。 The second problem is that it only extracts the words before and after space.第二个问题是它只提取空格前后的单词。 I want to extract keyword it from inside the word我想从单词中提取关键字
