用SOLR搜索短词 [英] Search for short words with SOLR
问题描述
我正在使用SOLR和NGramTokenizerFactory来帮助创建单词子串的搜索令牌
I am using SOLR along with NGramTokenizerFactory to help create search tokens for substrings of words
NGramTokenizer配置的最小字长为3
NGramTokenizer is configured with a minimum word length of 3
这意味着我可以搜索例如"unb"，然后匹配令人难以置信".
This means that I can search for e.g. "unb" and then match the word "unbelievable".
但是我对诸如"I"和"in"之类的简短单词有疑问.这些没有被SOLR索引(我怀疑是由于NGramTokenizer所致)，因此我无法搜索它们.
However I have a problem with short words like "I" and "in". These are not indexed by SOLR (I suspect it is because of NGramTokenizer) and therefore I cannot search for them.
我不想将最小字长减少为1或2，因为这会产生巨大的搜索索引.但我希望SOLR包括长度已低于此最小值的整个单词.
I don't want to reduce the minimum word length to 1 or 2, since this creates a huge search index. But I would like SOLR to include whole words whose length is already below this minimum.
我该怎么做?

推荐答案
首先，尝试了解为什么使用分析工具"无法通过solr为您的单词建立索引
First of all, try to understand why your words don't get indexed by solr using the "Analysis Tool"
http://localhost:8080/solr/admin/analysis.jsp
只需输入您要搜索的字段和文本，然后查看哪个分析器正在过滤您的短期交易.我建议您这样做，因为您说自己只有可疑"，并且必须确定哪个分析器可以过滤您的数据.
Just put the field and the text you are searching for and see which analyser is filtering your short term. I suggest you to do so because you said you have only a "suspect" and you have to be certain about which analyser filters your data.
那么，为什么不使用该分析器就直接将其复制到另一个字段中呢?
Then why don't you just simply copy the term in another field without that analyser?
通过这种方式，您的术语将被索引两次，并且将同时显示为准确的单词和n-gram. 然后，您必须处理两个不同字段的分数.
In this way your terms will be indexed twice, and will appear both as exact word and as n-gram. Then you have to deal with the scores of the two different fields.
我希望这对您有所帮助.
I hope this has helped you in some way.
