com.xpn.xwiki.store.XWikiHibernateStore.searchDocumentsNames supports a selectColumns parameter which is supposed to specify which columns should be selected.<br><br>This parameter is used when building the select string, but the columns are not included in the returned list, so this parameter just makes a bigger select string and increases the execution time.
<br><br>In order to include the specified columns in the result, I propose this:<br>- if selectedColumns is the empty string, keep the previous behavior (return a list of document names)<br>- if selectedColumns is not empty, then return a list of hashmaps, with the column name as the key, with a special name for the document name (for example docname)
