Where is FILTER option in Adobe Acrobat Pro - it was in previous versions?

[KPHD]

Upon upgrading from Adobe 9 to Adobe Acrobat Pro DC I no longer have the ability to FILTER pdfs (that are part of a portfolio) meeting a certain criteria (i.e. contain the word CONFIDENTIAL).  I would then delete the pdfs from the portfolio.  Where is my FILTER option in Adobe Acrobat Pro DC?  or in Adobe Acrobat X or IX? HELP!

Hi ctmwmom,

Please refer to this KB article (Kerwords 'Sort ,filter and change the order of files or folders ') :- Working with component files in a PDF Portfolio, Adobe Acrobat

Let me know if it works.

Thanks for the article.  Unfortunately it mentions a filter in the title but there isn't any mention of being able to "filter" in the body of the article.  I need to be able to pull pdfs meeting a certain criteria from the portfolio and the only way I've found to do this in Adobe Acrobat Pro DC is manually, one at a time.  I have 12,000 emails to go through for a Public Records Request.  I need to remove those marked "confidential".  In Acrobat 9 there was a filter and I could enter the word "Confidential" and it would display all positive results and allow me to delete from the portfolio.  Was this capability removed in this version?
