AND/OR logic

[PAVAN <pa...@gmail.com>]

Hi,

     I have situation that if user enters any string to search then i need
to display the results in the following way.

1. It has to match exact string what he entered.
     
              (or)

2. It has to split the string and search for individual keywords(for every
string) and it has to display the results.

Ex : suppose user searching for 

         "royal enfeild bikes"

First Condition----it has to check for whole string "royal enfiled bikes"
Second Condition ----- it has to display the results like   royal OR enfiled
OR bikes

Can anyone give me suggestions.

Is your requirement specifying that none of the alternative results should 
be shown if there are any primary results, or that the primary results 
should be shown first, or that both are acceptable?

You could do a phrase query for the full list of terms, and then do a second 
query with OR if the first returns no results.

Or, you could use a boost on the phrase and OR it with a de-boosted 
parenthesized OR query of the individual terms to show both but with the 
phrase matches first. If the natural scoring doesn't already boost the 
phrases enough by default.

You could also do that second approach by simply using the edismax query 
parser with the pf parameter to boost the phrase of all terms.
