How to perform a lucene query containing special character using QueryParser?

Question

Here is the thing. I have a term stored in the index, which contains special character, such as \'-\', the simplest code is like this:

Document doc = new Doc         


        

Answer 1

I am not sure about this , but I guess you need to escape - with \ . As per the Lucene docs.

The "-" or prohibit operator excludes documents that contain the term after the "-" symbol.

Again ,

Lucene supports escaping special characters that are part of the query syntax. The current list special characters are

+ - && || ! ( ) { } [ ] ^ " ~ * ? : \ /

To escape these character use the \ before the character.

Also remember, some characters you'll need to escape twice if they have special meaning in Java.
