Index custom calculated field

Suppose I have several fields (for example, two dates and a bolean, two boleans), and I want a new custom field that add some logic to this. For example


FieldA: bool
FieldB: bool

FieldC: is true when FieldA and FieldB

or another example

FieldA: date
FieldB: date
FieldC: bool

FieldD: FieldA < FieldB and FieldC


Can this be done? I guess I wouldn´t have too much problem making a custom field, but I don´t know if I´ll be able to filter by it later.

Hello

this will need authoring (programming) your custom field appropriately

you may duplicate an existing field and start coding

the other fields are available inside plugin code via:

e.g. with :
$item->fields
$item->fieldvalues

Ok, I´ll take a look at the code, I wasn´t sure about the "index me" part when is calculated
