Search Optimization Strategies

The strategies below handle the following in the search strings:

Different cases (i.e., case insensitive)
Stemming - reducing inflected (or sometimes derived) words to their stem (i.e. removes characters such as 'ing', 's', 'est')
Common misspellings
Word order (For example, Hanks, Tom vs Tom Hanks or duck horn vs horn duck)
Punctuation and other (usually) non searchable characters (these are ignored/stripped)

Example (Stemming and Case Insensitive):

If customer A searches for "shoes" and subsequently purchases product A, then

When customer B searches for "Shoes", the system will return product A.
When customer C searches for "Shoe", the system will return product A.

The strategies below will not handle synonym expansion.

RelatedToInternalSearch	12	"Items Related To Your Recent Search: '$STRATEGY_HINT$' "	Keys off of keywords from the search and correlates them with purchases. When the products are retrieved, products which match the most keywords will have their scores added together. When the products are written to the model, they are written for each term. The strategy will pull the products out and accumulate the scores for those products that match the most keywords. This strategy sees each individual word in a multi-word search as individual words.
