I flat guarantee that if you try to search on fields that are indexed
mixed case, you'll have no end of grief <G>. Everything from
mis-typed search requests to the same word being cased
differently in different parts of the source to ......
Your idea to index it twice is actually a solution that is often used.
Perhaps it'll relieve your nose to consider your storage and index
options <G>...
For example, index the field as Field.Store.NO, Field.Index.TOKENIZED
and search on that one.
For display, index as Field.Store.YES, Field.Index.NO
Even though you're breaking these into two fields, I don't think
your index size changes much. I know that was the hurdle I
had to get past to get comfortable with this....
BTW, how big do you expect your index to get anyway? It''s
one thing to be concerned about size if your index is many
gigabytes, but it's a needless worry if your index is under, say,
a gigabyte or so.

Hi Daniel,
I dont lowercase the field at index time, because I have to show the
results in the same way as it was found.
For instance:
Some fields indexed:
PP-Trip SubAlcance Seq Negativa
PP-Trip SubAlcance Seq Positiva
PS-Trip SubAlcance Seq Negativa
PS-Trip SubAlcance Seq Positiva
If I search for "PP-TRIP SUBALCANCE SEQ NEG", I want that the result
showed are:
PP-Trip SubAlcance Seq Negativa
PS-Trip SubAlcance Seq Negativa
Not:
pp-trip subalcance seq negativa
ps-trip subalcance seq negativa
A possible solution is store in a document object two fields: the
original
and the lowercased. I use the last one to make the query, and the other
one
to show the results. It works, but it doesnt smell good!
Thanks for your help!
