Search Engine By Phrase - Strange numbers in results

Help!

[topcoat]

I have run a full report on our site and there are some strange figures in the results.

Table: 'Activity by Search Engines with Search Phrases Detail'
Engine: Microsoft Network

I am seeing the following under 'Phrases'

8210516969256
8171610173944
8099770412279
8147522292425

They have various amounts of referrals. Anyone got any idea what they are and what they're doing in my report?

They only show under Microsoft Network and they also show in the table 'Activity by Search Engines with Keywords Detail'

Any help appreciated ;-)

Sorry, i'm using WebTrends Reporting Center - Enterprise Edition v6

looks similar to aol search query results which they encrypt with a hash..

might be something along the same lines?

I considered that they may be encrypted but if that was the case I would expect all the results from that engine to be similar. However, along with the numbers there are also a few normal keywords/phrases so I ruled that out.
