Looks like you have quotes inside quotes, which is syntactically incorrect. You can either use double quotes for the outside:

"where doc.space='Main' order by doc.date desc"

or double the single quotes inside:

'where doc.space=''Main'' order by doc.date desc'

I have tried both, but all failed, the error infomation is bellow: Failed to execute the [velocity] macroorg.xwiki.rendering.macro.MacroExecutionException: Failed to evaluate Velocity Macro for

I use $xwiki.searchDocuments(*'where doc.space='Main' order by doc.date desc *', 5, 0) to query for recently modified pages under a specific space "Main", but when I am executing it, error returns. Could anyone can tell me what is the problem with the query
