Hi,  
I have a span near query which returns certain result. Now I want to extract the tf/phasefreq. I don't want to parse. I am looking at writing a dynamic script (Groovy) to fetch it. So far I am not successful.  
Below is how the result looks like in explanation field and I want to fetch phraseFreq=0.33333334:  
"\_explanation": {  
"value": 0.03321779,  
"description": "weight(spanNear([text:really, text:nice], 0, true) in 0) [PerFieldSimilarity], result of:",  
"details": [  
{  
"value": 0.03321779,  
"description": "fieldWeight in 0, product of:",  
"details": [  
{  
"value": 0.57735026,  
"description": "tf(freq=0.33333334), with freq of:",  
"details": [  
{  
"value": 0.33333334,  
"description": "phraseFreq=0.33333334"  
}  
]  
},
