Hello all.

I have a question.  
For example, there are documents as following.

1. Love is blue.
2. Blue is love.
3. Red is not love.

In this case if I apply indexOf('Love'), result is as following.

1. Love is blue = index 0
2. Love is blue = index 8
3. Love is blue = index 12

Finally, I would like to compute score like following pseudo syntax.

script : "\_score \* sentence.indexOf(keyword)"

In ElasticSearch, is this possible?  
Please give me some advice.

Thanks for reading.

Hello.

I have resolved this issue.  
Following is a example to resolve my problem.

{"query":{"custom\_score":{"query":{"query\_string":{"query":"title:"Love""}},"script":"\_source.weight

- new String(\_source.title).indexOf("Love") \* 0.00001"}}}
