Meghana - Some important points about q/fq -
* q is used for scoring. fq is for filtering, no scoring. * fq and q are cached independently You may want to combine the user entered terms (search term, title, and desc) in the q parameter. It's complicated/advanced, but you can use nested queries to achieve a spread of different query contexts with different field configurations.
