sample method:
{code}
public static File createPrimaryTypeSynonymsFile(String path, Session session)
throws Exception {
File file = new File(path);
StringWriter stringWriter = new StringWriter();
NodeTypeIterator allNodeTypes =
session.getWorkspace().getNodeTypeManager().getAllNodeTypes();
while (allNodeTypes.hasNext()) {
NodeType nodeType = allNodeTypes.nextNodeType();
NodeType[] superTypes = nodeType.getSupertypes();
if (superTypes != null && superTypes.length > 0) {
stringWriter.append(nodeType.getName()).append(" => ");
for (int i = 0; i < superTypes.length; i++) {
stringWriter.append(superTypes[i].getName());
if (i < superTypes.length - 1) {
stringWriter.append(',');
}
stringWriter.append(' ');
}
stringWriter.append('\n');
}
}
FileOutputStream fileOutputStream = new FileOutputStream(file);
fileOutputStream.write(stringWriter.toString().getBytes("UTF-8"));
fileOutputStream.flush();
fileOutputStream.close();
if (file.exists() || file.createNewFile()) {
return file;
} else {
throw new IOException("primary types synonyms file could not be
created");
}

> Add a utility method to create Solr synonym file for node type expansions

> Key: OAK-2009
> URL: https://issues.apache.org/jira/browse/OAK-2009
> Project: Jackrabbit Oak
> Issue Type: Improvement
> Components: oak-solr
> Reporter: Tommaso Teofili
> Assignee: Tommaso Teofili
>
> Currently Solr supports filtering by node types but it's not aware of the
> node type hierarchy therefore searching for nt:file doesn't expand to
> searching for nt:base and nt:hierarchyNode for example. So either we make
> this dynamic (which would be possibly slow) or we leverage synonym expansion
> and build the synonym file from the node type hierarchy once and use that
> when indexing/searching, the open problem is how to deal with changing node
> types.
