solr search results not coming as expected

Hi Team,

We have one of the attribute related to product which is named as ctnIdentifier. This attributes is the unique for product. I have added this attribute for autocompletion text in solr impex. i have added this property attribute for boosting the search. This attribute ctnIdentifier has the highest boosting property. still it is not giving the results which is based on this attribute. suppose for example when i search for abcde123 take as ctnidentifier. i am not getting this search result as first result. search results still we are getting based on the code itself. Please help me in resolving this issue asap.

Thanks & Regards
