Answer 19: LSI indexing ries to overcome the limitations of "literal" search term matching . For example, if someone is searching for "hiking in Norhter Nevada" a literal search would only match the words used without taking into account words such as "hike", "hiked". LSI can give more relevant results because it does take word usage and context into account determining what a page is "about" rather than a strict reliance on literal wording.

Answer 20: regards to search results, it is a method that search engines such as google use to determine relevance of a page based on phrases actually used in a document. For example, if you have a page instructing people on wildlife photography, the search engine would reasonably expect to see terms and phrases such as "selecting a camera", "approaching wildlife", and "low light photo conditions". Related phrases will add to the relevance of a page where unrelated phrases will reduce the relevance of a page. This is one technique that Google is using to weed out "spam" sites.
