Using a Query Classifier to dynamically boost Solr ranking
About 40% of our queries are ambiguous, which can result with products from many categories. For example, the query "red apple" can match the following products:

1. red apple ipod (electronic category)
2. red apple fruit ( fresh produce )
3. red apple iphone case ( accessories)

It is desirable to have a classifier to instruct Solr to boost items from the desire category. In addition, for a search engine with small index, a good percentage of the queries may have little or no results. Is it possible to use the classifier to solve both problems?

This talk discusses a classifier built from behavior data which can dynamically re-classify the query to solve both problems.
