If the Web is evolving, searching the evolving Web must also evolve. A few days ago, AltSearchEngines summarized a few viewpoints on how Web search may evolve from Search 1.0 to Search 3.0 and further. I, however, want to add one more thought on this topic from my vision of Web evolution.

What is Web search? There may be varied answers. I believe, however, Web search is the process of producing proper Web link resources that match specified requests. Following this definition, every evolutionary stage of Web search can be uniformly determined by the quality of its produced link resources. In specific, Search 1.0 means the produced link resources are 1.0-level quality, Search 2.0 means the produced link resources are 2.0-level quality, and so on.

The quality of link resources on behalf of Web evolution is not how precisely the search results match the search query request. Such precision is a quality measurement but in another meaning that is, however, unrelated to Web evolution.
