Alfresco : How to search for a specific files types?

Question

I am working to search all PNG files(ie all files which has file name extension ".png") in alfresco. I am using the followingcode, but it does not return any result:

var docs = search.luceneSearch("@cm\\:content.fileType:\"*.png\""); 
for (var i=0; i<docs.length; i++)
   {
     //TO print the name of files--> "Name: " + docs[i].name ;

   } 

I am not sure if content.fileType is the right way to code to search for file types. Any suggestion please ?

Answer 1

You should go with the content.mimetype query, for example: @\\{http\\://www.alfresco.org/model/content/1.0\\}content.mimetype:text/plain

Answer 2

如果使用此语句，则仅查找PNG图像会有所帮助：

var docs = search.luceneSearch("@cm\\:name:\"png\"");

Answer 3

If your really want to search for PNG files you should follow Lista's approach using mimetype but with correct syntax

var docs = search.luceneSearch("@cm\\:content.mimetype:\"image/png\"");

searching for name part "PNG" ("@cm\\:name:\\"png\\"") would find any document having a token "PNG" in it's name like png.name.pdf or any_png.doc since document name is stored tokenized in the index
