pdf content cannot be searched

[peacechan]

Dear all,

I installed Letodms in my RS3614xs, everything went well and i installed ipkg and loaded packages like pdftotext, catdoc etc.
When i run from command line, pdftotest abc.pdf convert to abc.txt file but when i try to search from the GUI, i can only search the content from .txt files but not from the .pdf neither from .docx or .xls .
When i check the full text indexinfo there i see the content from .txt fille but not from doc, pdf or xls files .

Can you pls anyone help me to search the content of pdf,doc,excel etc files??
Thanks in advance
