问题描述
我正在尝试在Lucene中匹配多个单词，就像在MySQL中一样.
I'm trying to match multiple words in Lucene as I could do in MySQL.
这比我想的要难:
用PHP编写:我对完美匹配的查询是:
written in PHP:my query for perfect match is:
$words = explode($words, " ");
(text:(' . implode(" ", $words) . ')
但是如果文本是我写的一堆单词"，那么直到我写完所有内容后，文本才会匹配
but if text is "a bunch of words I wrote", it won't match until I have written everything
是否存在强迫Lucene完全像MySQL一样的％a bunc％"行为并检索漏洞短语的方法?
Does exist any way to force Lucene to behave exactly like MySQL's like "%a bunc%" and retrieve the hole phrase?
预先感谢
我不是直接使用Lucene，而是将Solr用作REST服务.因此，我正在寻找普通语法"来解决此问题，例如:select?q = :并且查询为:(全选)(如果我有很多单词的话)如前所述，在文本字段中，我找不到任何将它们视为唯一词的方法.如果这是一个独特的词，我可以执行"text:(beginningOfW *)"，它将找到它，如果是多个单词，如果我写"text:(W *开头)"，它将仅找到以W开头的单词，而忽略其他单词.
I'm not using Lucene directly, I use Solr as a REST service. So I'm looking for the "plain grammar" to solve this problem like: select?q=: and the query is : ( select all ) if I have many words in the text field, as told before, I don't find any way to consider them as a unique word.If it were a unique word, I could do "text:(beginningOfW*)" and it would find it,If it is a multiple words, If I write "text:(beginning Of W*)" it will find only words beginning with W, and ignore the other words.
推荐答案
是的，Lucene是全文搜索引擎API.我认为您正在寻找WildCardQuery:
Yes, Lucene is full text search engine API. I think you are looking for WildCardQuery:
Term term = new Term("whichField", "searchString");
Query query = new WildcardQuery(term);
Hits hits = indexSearcher.search(query);
