If a document value is "jerry tom micky"  
it has to be anlayzed and stored as below  
"jerry tom micky"  
"jerry micky tom"  
"tom micky jerry"  
"tom jerry micky "  
"micky jerry tom"  
"micky tom jerry"

Any idea to achieve this?

Hi @tamil,

I fear it is not possible to store this as this would lead to a combinatorial explosion and hence an insanely huge index. Just consider what would happen if one document contained just 20 words. This would lead to 20! = 2432902008176640000 combinations.

But maybe there is another way to solve this problem. Can you please describe what you want to achieve?

Daniel
