Hi Francesco,

Hi Adrian, thanks for your contribution!
I have already commented there.
Be aware that :
1. it's a global case insentive flag (and not a fiql operator).
There were 2 reasons for this:
* creating a custom fiql operator isn't possible for the moment
without either modifying cxf fiql parser or writing another (which
would be a pity).
* I had some exchanges with Sergey on case-insensitivity search . His
view on this case in/sensitivity issue is that it can be resolved by
configuration (I took this approach - easier :) ).
After looking a bit SCIM spec, https://tools.ietf.org/html/rfc7643,
there's a lot (majority) of fields with caseExact=false. So on second
thought I think too that we can live with a global flag.
Just let me know if this limitation is ok for you.
Hum, I would rather prefer not being forced to globally decide how EQ
and LIKE comparisons are working for all search queries.
I not, we'll need to add some more exchanges with Sergey or you'll
need to show me how you could use custom fiql operators, because I
don't see them.
2. case insensitivity is only implemented for fiql search.
Let me know if you think that we need also implement it in other
search (I think only groupDao.findByXXX, userDao.findByXXX would need).
No need for this: such methods are only used internally.
Also just let me know if you see anything in this PR that's not ok for
you !
Please check the comments there.
Regards.

We can solve it using jpql LOWER ou UPPER function, i.e.
LOWER(givenName) = LOWER('Martin')
I can try to implement it, but I don't know for now if it is possible
to introduce either :
* custom operator in FIQL (i.e. some eqi operator like : givenName
eqi Martin)
* introduce custom functions in FIQL (i.e. uc(givenName) == uc(Martin))
I would rather go with first (we also have other custom operators).
Essentially, I see two separate tasks here:
1. extend FIQL, the query builders and the logic that transforms FIQL
queries into the low-level search objects
2. extend JPAAnySearchDAO to take care of such new EQI comparator,
similarly to what is currently done at
https://github.com/apache/syncope/blob/2_0_X/core/persistence-jpa/src/main/java/org/apache/syncope/core/persistence/jpa/dao/JPAAnySearchDAO.java#L782-L790
The only non-obvious problem I see is that we will need to make the
new code RDBMS provider dependent.
Sorry, totally missed your statement above about using JPQL's LOWER()
or UPPER() - smart move ;-)
Sorry again: the problem is that queries built by JPASearchDAO are
native query, not JPQL.

Hello,
I'd like to execute a case insensitive search in Syncope.
i.e. querying all users with an attribute givenName that matches
'martin' would return :
Martin
martin
mArtin
Is there a way to do this with a Fiql search ?
i.e. something like UPPER(givenName) = UPPER('martin') ?
If no are there other ways to do this ?
If no, I can always store givenName attribute in 2 different
attributes (i.e. the real givenName attribute and a
givenNameCaseInsensitive attribute to store it in lowercase), but
I would like to avoid it if possible.
Hi Adrian,
I confirm that currently it is *not* possible to perform case
insensitive searches.
Nevertheless, it would be a nice feature to add: essentially, one
should be adding 'lowercase()' clauses to the native SQL queries
manage by [1]: the problem is that, as far as I can tell, such
clauses are DBMS-dependent.
Would you mind creating an improvement on JIRA for this?
Naturally, contributions are welcome ;-)
Regards.
