Google serves some 80 percent of all search queries on the Internet, mak - ing it by far the most popular search engine. Its popularity is due not only to excel - lent search effectiveness, but also extensive querying capabilities. However, we should also remember that the Internet is a highly dynamic medium, so the results presented by Google are not always up-to-date – some search results might be stale, while other relevant resources might not yet have been visited by Googlebot (the automatic script that browses and indexes Web resources for Google). Table 1 presents a summary of the most important and most useful query operators along with their descriptions, while Figure 1 shows document locations referred to by the operators when applied to Web searches. Of course, this is just a handful of examples – skil - ful Google querying can lead to much more interesting results.
