问题
I'm using this search
-> match (c1, c2) against (">dg*" in boolean mode);
and I get this list
1 dgas
2 dgica
3 dgicb
4 dgii
5 dgit
6 dgly
7 dgc
8 dgse
which seems reasonable.
The problem is that I DON'T get "dgl", which I know is there in column c1.
So I DO get "dgly" but NOT "dgl".
I find this confusing and would appreciate any thoughts. Thanks.

MySQL fulltext indexing will, by default, ignore words that are shorter than four characters.
This can be changed at the server level by setting ft_min_word_len to a smaller number and then rebuilding the fulltext indexes.
Here's more information in the manual about fine-tuning fulltext searches.
