问题
Is there any method to search content of binary files like PPT, PDF etc other than
converting it into X HTML format using xdmp:document-filter() function and searching on it ?
回答1:
Basically no. You have to pull out the readable text out of the binary format to allow MarkLogic to index it. You can extract that text with xdmp:document-filter() or with functions like xdmp:pdf-convert() and xdmp:word-convert(), but there is no way to index binary nodes directly.
HTH!
