------------------------------------
Hi,
I'm adding another example to try to describe the point of having unique names,
to make it easier for future usage.
Below is another (seudo java) example.
The example uses 2 diferent SyntaxParser implementations,
but it use only one ProcessorPipeline and one QueryTreeBuilder implementation
to create a single lucene Query.
String uiquery = "a AND b";
SyntaxParser ssp = new StandartSyntaxParser()
QueryNode tree = ssp.parse(uiquery);
QueryNode filter = new XMLSyntaxParser("<name='area' code='408'>");
QueryNode bqn = new AndQueryNode();
bqn.add(ssp);
bqn.add(filter);
QueryNodeProcessor spp = new StandartProcessorPipeline(config);
QueryNode optimizedTree = spp.process(bqn);
Query q = builder.build(optimizedTree);
> Rename OriginalQueryParserHelper

> Project: Lucene - Java
> Issue Type: Improvement
> Components: contrib/*
> Affects Versions: 2.9
> Reporter: Michael McCandless
> Assignee: Michael McCandless
> Priority: Minor
> Fix For: 2.9
>
> Attachments: LUCENE-1782.patch
>
>
> We should rename the new QueryParser so it's clearer that it's
> Lucene's default QueryParser, going forward, and not just a temporary
> "bridge" to a future new QueryParser.
> How about we rename oal.queryParser.original -->
> oal.queryParser.standard (can't use "default": it's a Java keyword)?
> Then, leave the OriginalQueryParserHelper under that package, but
> simply rename it to QueryParser?
> This way if we create other sub-packages in the future, eg
> ComplexPhraseQueryParser, they too can have a QueryParser class under
> them, to make it clear that's the "top" class you use to parse
> queries.
