Solr的常见问题提到本作的BLOB <一个href=\"http://wiki.apache.org/solr/DataImportHandlerFaq#Blob_values_in_my_table_are_added_to_the_Solr_document_as_object_strings_like_B.401f23c5\" rel=\"nofollow\">http://wiki.apache.org/solr/DataImportHandlerFaq#Blob_values_in_my_table_are_added_to_the_Solr_document_as_object_strings_like_B.401f23c5
Solr FAQ mentions this for the blob http://wiki.apache.org/solr/DataImportHandlerFaq#Blob_values_in_my_table_are_added_to_the_Solr_document_as_object_strings_like_B.401f23c5

有是一个对促进该BlobTransformer JIRA问题，但不似乎要把它变成code。您可以参考该补丁，并挑选可能是你使用的变压器。
There was an JIRA issue for contributing the BlobTransformer, but doesn't seem to make it into the Code. You can refer the patch and pick the transformer for your use probably.
不知道其改名/重构/在当前版本中改名为不同的。
Not sure if its renamed/refactored/renamed differently in the Current versions.
