Hi Barath,
The MATLAB function "fieldsearch" can be used to find Bloomberg fields of interest based on key words. "fieldinfo" can give further information describing a given field. In this case, I would suggest using "fieldsearch" and "fieldinfo" to find the name of the field you are looking for, then creating a "lookup" query in order to actually retrieve the data.
Here are the documentation pages for "fieldsearch" and "fieldinfo":
Best of luck,
Nate
