He also notes that despite AlltheWeb and AltaVista now using the Yahoo database, results for the three engines still differ for the same query, though the divergence appears to be narrowing...

Search ranking and results vary significantly with plurality. For example, using the ranking tool to compare "business" and "businesses" within Google shows very little correlation between results.This suggests that the ranking tool can actually help searchers improve their queries, by running simple variations at the same time and comparing results.

Ranking also varies significantly with reversal of keywords. For example, using the tool to compare "allergy treatment" and "treatment allergy" within Yahoo returns very different results.

Search ranking and pages returned as results also changes significantly with the addition of a single related keyword. For example, comparing "freeware" and "freeware software" within Teoma yields only a 30% overlap, though interestingly, many of the top ten results are highly correlated."
