Scoring partial match in title field higher than exact match in description field

[nileshwagh24]

In need to score partial match in NAME field higher than exact match in
INFOTEXT field.Actually I need to sort my SOLR result based on following
five conditions

1.First, results with a whole word match on the first or second word in the
NAME go on top.

2.Then, results with a whole word match elsewhere in the NAME.

3.Then, results with a partial word match anywhere in the NAME.

4.Then, results with a whole word match in the INFOTEXT.

5.Finally, results with a partial word match in the INFOTEXT.

 I have added descriptionExact field for INFOTEXT and titleExact field for
NAME.

For this I have added four fields like
titleExact,titlePartial,descriptionExact,DescriptionPartial and boosted
titleExact score higher than all others.

But I am not getting result as expected.

Following are the field definitions for exact and partial field
