Is there any way to search within a portfolio ?
Dollar Photoclub had much better functionality with searches.
While Adobe hasn't designed the site well for searching beyond the most basic of searches, you CAN search for specific keywords within a given portfolio, you just need to know how to edit the actual URL and what the URL for a search looks like.

Notice how there is a pattern in the queries of data_field=item
You combine queries with an ampersand (&). So to search for just zombie hands in this particular portfolio, you would enter the portfolio and add "&k=zombie+hands" to the end of the URL, looking like this:
Voila! Searching within a portfolio. The actual coding behind the site allows for more powerful search strings. It's just the interface that doesn't show these options.
