Lucene查询语法搜索

Question

Total novice when it comes to Lucene Query Syntax so need a bit of help!

Searching a database by email and using

email: <someone's email here>

in the URL as the search param.

How would one go about implementing this so it would only return the record with the exact email address?

So if I were to search

email: test@gmail.com

and the database contained a 'test@email.com' and 'test@gmail.com' only the latter would be returned?

I've had a look at http://www.lucenetutorial.com/lucene-query-syntax.html however the answer eludues me.

Any help would be much appreciated as always!

This is analyzer's question.

If you want search the exact word, you should build the address field with Field.Index.NOT_ANALYZED , then the address "test@email.com" will be analyze to "test@email.com".

The code like this：

Document doc = new Document();
doc.add(new Field("email", "test@email.com", Field.Store.YES, Field.Index.NOT_ANALYZED));
