Why does LexiURL Searcher sometimes return less than the estimated number of results, even for searches with less than 1,000 matches?
There are two reasons why the number of URLs returned (under 1000) is often less than the number of estimated matches. The first is that duplicates can be ignored – and this also extends to near duplicates, or pages that are similar around the text that would be returned by the search engine as the page description snippet. The second reason is that a maximum of two hits per web site are normally returned unless you select the “disable host collapsing” search option in LexiURL Searcher.
