Creates a lucene Query tree from an abstract query tree.

Parameters:

qomTree - the root of the query object model.

session - of the user executing the query.

sharedItemMgr - the shared item state manager of the workspace.

nsMappings - namespace resolver for internal prefixes.

analyzer - for parsing the query statement of the contains function.

propReg - the property type registry to lookup type information.

synonymProvider - the synonym provider or null if node is configured.

bindVariableValues - the bind variable values.

version - the index format version.

Returns:

the lucene query tree.

Throws:

javax.jcr.RepositoryException - if an error occurs during the translation.
