Hi Halian,

The number after the dot (.) is the version number of the transcript. 
For example, see: 
http://uswest.ensembl.org/Homo_sapiens/Transcript/Idhistory?db=core;g=ENSG00000223972;r=1:11869-14409;t=ENST00000456328

For searching, yes, just remove the dot (.) and the version number.


Please let us know if you have any additional questions: [email protected]
