ML-Driven Search to Power Your Modern Data Strategy by Karen Kilroy pdf download.
Search engines are a type of database solution that allow you toquery both structured and unstructured information to retrieve relevant matches.Most search applications use more than just thetext you type into the search box:they also employ filters and facets,information on your past interaction with the application
(personalization)，information about how other users interacted withthe data,and much more.
When your customers use a search application-for example,to finda product they want to buy-they engage in an iterative process.
They send a query,examine the results,and refine the query to getthe right information.On the backend,the application formats all theelements of the interaction into a query couched in the query language provided by the search engine.Reviewing the new resultsand continuing through this cycle (as shown in Figure 1-1) is how customers traditionally use search engines to narrow down the itemsthat interest them.
