Adriano Crestani updated LUCENE-1823:

We can also implement:

    * foo~(>=1) should really just map to foo.

details in LUCENE-950 issue.

This patch fixes on the contrib/queryparser this bug as discussed on LUCENE-950. It does not
throw IllegalArgumentException anymore for fuzzy values greater or equals 1, it just ignores
the fuzzy and create a simple field query. JUnits are also included.

I used 'ant javacc-contrib-queryparser' to regenerate the StandardSyntaxParser with javacc
4.2.

> 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
