How you can best use the occurrences operators (and the examples shown in Table 5-2) may take a bit of getting used to The following sections offer a bit more explanation

Suppose you want your search to return only pages that are the target of links when the link text matches your search To do so, you can use the allinanchor: and inanchor: operators These operators search only text that consists of clickable links on Web pages

Another way of putting this is that the text being searched falls inside <a> </a>, or anchor, tags in the underlying HTML Less formally, an anchor is a term or phrase that identifies a document in a noncomputerese language so that when people click the link they know what they re getting Few Webmasters would write an anchor like Mr McGee s Fishing Site if they were linking to wwwacmeknittingcom; an anchor such as Visit Acme Knitting would be more probable Because anchor text is reasonably likely to contain a straightforward description of the content of the page being linked to, using anchor text for pinpointed research often makes good sense, even though the return result is the site being linked to (for example, wwwacmeknittingcom) To take this a little further, if you already know you are interested in Acme Knitting, it s easy to end up on the Acme Knitting site But suppose you want to find the best site about knitting in general A search for

returns pages that are the targets of links that have the keyword knitting in link text somewhere on the Web pages, including Acme Knitting The order of the search results tells you the most-linked sites a gauge of popularity, and a rough indicator of quality on the Web In another example, suppose a Web page contains a whole bunch of text and the phrase Times Square in New York is a clickable link If you want to find all Web pages that are linked to with anchors that contain the words New York Times in clickable links, you use the allinanchor: operator, along with the three words New York Times in your search; the page linked to by the Times Square in New York anchor shows up in the results set The allinanchor: and inanchor: operators are probably the most useful of the occurrences operators, but they can also be the most difficult to wrap your brain around The anchor operators match a keyword, multiple keywords, or a search phrase with the text that accompanies a hyperlink The returned page is the one pointed to by the hyperlink, not the one containing the text For example, suppose that the HTML for the page wwwbraintiquecom (like thousands of other sites) contains a link to the New York Times Web site (wwwnytimescom):

I get my news from the <a href= http://wwwnytimescom >New York Times</a>!

An allinanchor: search for the phrase New York Times:
