One of the basic needs a search engine should support is a keyword search, as that's the primary goal behind the search engine platform. In fact it is the first thing a user will start with. Keyword search is the most common technique used for a search engine and also for end users on our websites. It is a pretty common expectation nowadays to punch in a few keywords and quickly retrieve the relevant results. But what happens in the backend is something we need to take care of to ensure that the user experience doesn't deteriorate. Let's look at a few areas that we must consider in order to provide better outcomes for search engine platforms using Solr:

• Relevant search with quick turnaround
• Auto-correct spelling
• Auto-suggestions
• Synonyms
• Multilingual support
• Phrase handling—an option to search for a specific keyword or all keywords in a phrase provided
• Expanded results if the user wants to view something beyond the top-ranked results

These features can be easily managed by Solr; so our next challenge is to provide relevant results with improved user experience.
