More specifically look for the "Query Syntax" documentation entry for the Lucene Core version matching the version used in your XWiki installation (to find the version used by XWiki look for ##lucene-core-x.y.z.jar## in the XWiki's ##/WEB-INF/lib## folder. For example for XWiki Enterprise 2.6 uses Lucene Core 2.9.3 which means the Lucene Query Syntax can be found [[here>>http://lucene.apache.org/java/2_9_3/queryparsersyntax.html]].
