Multiple non-host client sites provide cached user copies of web pages and/or web content, or summaries thereof, to a server. Obtaining data from non-host sources for indexing purposes avoids masked web page content indexing errors for search engines. The server aggregates, summarizes and indexes the web pages and/or web content in an index of cached content, in conjunction with updating, generating and storing a search index using an indexing agent such as a web crawler or spider. In response to receiving search requests from end users, the search engine uses comparisons between the index of cached content and the index of crawled content to identify potential page masking errors for specific search results and appropriately rank or omit results with a high risk of masking errors in a search result list.
