+    <b>[6.15] I want to add a BLOB field and put an index on it, but MySQL
+    says &quot;BLOB column '...' used in key specification without a key 
+    length&quot;.</b>
+    <br />
+    The right way to do this, is to create the field without any indexes,
+    then display the table structure and use the &quot;Create an index&quot;
+    dialog. On this page, you will be able to choose your BLOB field, and
+    set a size to the index, which is the condition to create an index on
+    a BLOB field.
