解释Lucene的查询

Question

I was wondering if there is any way to interpret Queries of Lucene in simple terms?

For example :

Example # 1:

Input Query - name:John

Output - Interpreted as : Find all entries where attribute "name" is equal "John".

Example # 2:

Input Query - name:John AND phoneNumber:1234

Output - Interpreted as : Find all entries where attribute "name" is equal to "John" and attribute "phoneNumber" is equal to "1234".

Any tutorials in this regard will be helpful,

Thanks

The Lucene documentation does a pretty decent job in explaining basic queries and their interpretation. It seems as though that's all you're looking for; once you get into some of the more advanced query types, it gets hairy, but the documentation should always be your first stop; it's fairly comprehensive.

Edit: Ah, you want automated query explanation. I don't know of any that currently exist; I think you'll have to write your own, but if you're starting with standard QueryParser Syntax, I think the best input for your interpreter would be the output of QueryParser.parse() . That breaks down the free text into Lucene query objects that shouldn't be too difficult to wrap in a utility function that outputs a plain-English string for each one.
