If you are using XPath, you must use the rep:excerpt() function in the last location step, just like you would select properties:

QueryManager qm = session.getWorkspace().getQueryManager();

Query q = qm.createQuery("//*[jcr:contains(., 'exoplatform')]/(@Title|rep:excerpt(.))", Query.XPATH);

QueryResult result = q.execute();

for (RowIterator it = result.getRows(); it.hasNext(); ) {

   Row r = it.nextRow();

   Value title = r.getValue("Title");

   Value excerpt = r.getValue("rep:excerpt(.)");

}

The above code searches for nodes that contain the word exoplatform and then gets the value of the Title property and an excerpt for each result node.

It is also possible to use a relative path in the call Row.getValue() while the query statement still remains the same. Also, you may use a relative path to a string property. The returned value will then be an excerpt based on string value of the property.

Both available excerpt provider will create fragments of about 150 characters and up to 3 fragments.

In SQL, the function is called excerpt() without the rep prefix, but the column in the RowIterator will nonetheless be labled rep:excerpt(.)!

QueryManager qm = session.getWorkspace().getQueryManager();

Query q = qm.createQuery("select excerpt(.) from nt:resource where contains(., 'exoplatform')", Query.SQL);

QueryResult result = q.execute();

for (RowIterator it = result.getRows(); it.hasNext(); ) {

   Row r = it.nextRow();

   Value excerpt = r.getValue("rep:excerpt(.)");

}
