Namespace Lucene.Net.QueryParsers.Flexible.Core.Parser

Necessary interfaces to implement text parsers.

Parser

The namespace Lucene.Net.QueryParsers.Flexible.Core.Parser contains interfaces that should be implemented by the parsers. Parsers produce IQueryNode Trees from a string object. This package still needs some work to add support to for multiple parsers. Features that should be supported for the future, related with the parser:

• QueryNode tree should be able convertible to any parser syntax.
• The query syntax should support calling other parsers. - QueryNode tree created by multiple parsers.

Interfaces

IEscapeQuerySyntax

A parser needs to implement IEscapeQuerySyntax to allow the IQueryNode to escape the queries, when the ToQueryString method is called.

ISyntaxParser

A parser needs to implement ISyntaxParser interface

Enums
