two different field/facet id for Transcriptomics

[baimingze]

Hi guys, when I use this url:
http://www.omicsdi.org/ws/dataset/search?query=(omics_type:(Transcriptomics)%20AND%20disease:(breast*%20cancer))&facetcount=100&size=15&sortfield=&order=descending&start=0

I have got:

"facetValues":[
{"label":"Transcriptomics","value":"Transcriptomics","count":"59"},
{"label":"Multi-Omics","value":"Multi-Omics","count":"9"},
{"label":"Transcriptomics","value":"transcriptomics","count":"8"}]}

Could you merge them in to one value for "Transcriptomics"?
