If I enter a keyword with the characters like "/" or "*" in search, then it does not display the description in search results.
For eg: Check out the page http://www.photopost.com/photopost/s....php?photo=860
which has the character * in its description.
If I search for keywords "dream" or "*", it shows up for both the searches, but in case of "*", it does not display the description.
This might be happening for many many such special characters.
If your search results ids are stored for many days, then the following searches may still be active:
[Search "dream" - Results are displayed with description]
[Search "*" - Results are displayed without description]
In both cases photo=860 is the 1st result.
Same thing is happening to my installation.
