     [ https://issues.apache.org/jira/browse/SOLR-3039?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]

Danny Dvinov updated SOLR-3039:
-------------------------------

    Attachment: SOLR-3039.patch

Changes include:
- Making ExtendedDismaxQParser public to allow implementations that can extend it (and pulling it out into a separate file, ExtendedDismaxQParser.java).
- Making ExtendedSolrQueryParser protected to allow to allow implementations that can extend it.
- Introducing 3 protected methods on ExtendedDismaxQParser to allow implementations that extend ExtendedDismaxQParser to override some of the behavior:
1. ExtendedSolrQueryParser getQueryParser to allow specifying the parser used to parse the query.
2. boolean includeClause(Clause clause) to allow overriding whether given clause should be part of the {@link org.apache.lucene.search.Query} being parsed.
3. String preProcessUserQuery(String queryString) to allow pre-processing the query string prior to parsing.

> ExtendedDismaxQParser.parse does not currently allow for things like query pre-processing prior to its parsing, specifying the parser to be used, and whether particular clause should be included in the query being parsed. Furthermore, ExtendedDismaxQParser and inner ExtendedSolrQueryParser cannot be subclassed. By resolving this issue, we'll provide a way for Solr implementations to extend the parser and parsing related behavior.
