[BiO BB] How can I retrieve the biggest transposable element from NCBI?

[水 稻]

    I want to retrieve the sequence of the biggest transposable element 
from NCBI.  Can anybody tell me what's the proper steps?  
    I've try to do it by searched nucleotide databases in NCBI with keyword 
"transposable element", but most records of what I retrieved was 
irrespective.  Another problem is how can I distinguish the biggest 
transposon from others before I download all the sequences.  After all, 
nearly 8000 records is rather large. 
   I'll be so glad if anyone tell me better ways to achieve the aim. Thanks.
