Web search engines slow on the update

摘要

A researcher has uncovered serious shortcomings in how web search engines update their databases.None of the search engines in a study by Dirk Lewandowski updated their results on the same day as there was a change in the web pages they were indexing."There's simply no use in indexing a page daily if the search engine is not able to show this as a result on the same day,"said Lewandowski.
