The previous sections described the general query and filtering process focusing on a full-history search that happens for every chunk. There are a couple additional queries that use the same structure as above, but provide a different set of results. | |||
The first is adaptive learning that shows pages that users have previously selected from the autocomplete when typing a similar query. The query is slightly different as it uses another table to look up previous query->page mappings, but it goes through the same filtering process. | |||
The second special query is to show smart keyword searches, where the first token in the query is the keyword and other tokens are additional search parameters. We look in the bookmarks database to find a matching keyword and insert the search parameters into the "%s" portion of the bookmark url. | |||
