Same problem here!!!
A make the search with the main keywords (the first) of all my photos, and never shows in the results.
In some cases shows only 3 or 4 photos, but the ones i did never appears.

I contacted the support but there is no answer...

for example.
https://ar.fotolia.com/id/123495983

The 3 most relevant keywords are barrel, gun, knot (in adobe stock, these are the 3 first)

If you make that search
https://ar.fotolia.com/search?k=barrel%2C+gun%2C+knot&filters%5Bcontent_type%3Aall%5D=1&search-submit=Buscar

it shows 12 results... but never the one i did...

am i missing something?
Am i doing something wrong?

Thanks guy!
Lean.
