2 Opaque terms

I propose the following examples for the syntax
{code}
syntax1:
+a -b ::complexPhrase('other syntax') ::xml('/bookstore/book[price>35.00]')
::googlesyntax('2..20 doughnuts')
syntax2:
+a -b complexPhrase::'other syntax' xml::'/bookstore/book[price>35.00]'
googlesyntax::'2..20 doughnuts'
syntax3:
+a -b complePhrase:'other syntax' xml:'/bookstore/book[price>35.00]'
googlesyntax:'2..20 doughnuts'
{code}
We can also have a default SyntaxExtension to make the syntax easier, for
example if complexPhrase was the default Syntax Extension,
the queries above could be written like this:
{code}
syntax1:
+a -b ::('other syntax') ::xml('/bookstore/book[price>35.00]')
::googlesyntax('2..20 doughnuts')
syntax2:
+a -b ::'other syntax' xml::'/bookstore/book[price>35.00]' googlesyntax::'2..20
doughnuts'
syntax3:
+a -b 'other syntax' xml:'/bookstore/book[price>35.00]' googlesyntax:'2..20
doughnuts'
{code}
I would like to call it Query Parser Syntax extensions instead of Opaque Terms.

> QueryParser with new features for Lucene 3
> ------------------------------------------
>
> Key: LUCENE-1823
> URL: https://issues.apache.org/jira/browse/LUCENE-1823
> Project: Lucene - Java
> Issue Type: New Feature
> Components: QueryParser
> Reporter: Michael Busch
> Assignee: Michael Busch
> Priority: Minor
> Fix For: 3.1
>
>
> I'd like to have a new QueryParser implementation in Lucene 3.1, ideally
> based on the new QP framework in contrib. It should share as much code as
> possible with the current StandardQueryParser implementation for easy
> maintainability.
> Wish list (feel free to extend):
> 1. *Operator precedence*: Support operator precedence for boolean operators
> 2. *Opaque terms*: Ability to plugin an external parser for certain syntax
> extensions, e.g. XML query terms
> 3. *Improved RangeQuery syntax*: Use more intuitive <=, =, >= instead of []
> and {}
> 4. *Support for trierange queries*: See LUCENE-1768
> 5. *Complex phrases*: See LUCENE-1486
> 6. *ANY operator*: E.g. (a b c d) ANY 3 should match if 3 of the 4 terms
> occur in the same document
> 7. *New syntax for Span queries*: I think the surround parser supports this?
> 8. *Escaped wildcards*: See LUCENE-588
